Plot

After a selfish L.A. yuppie learns his estranged father left a fortune to an autistic-savant brother in Ohio that he didn't know existed, he absconds with his brother and sets out across the country, hoping to gain a larger inheritance.

Charles Sanford "Charlie" Babbit is a self-centered Los Angeles-based automobile dealer/hustler/bookie who is at war with his own life. Charlie, as a young teenager, used his father's 1949 Buick convertible without permission and as a result, he went to jail for two days on account that his father reported it stolen. It is then that Charlie learns that his estranged father died and left him from his last will and testament a huge bed of roses and the car while the remainder will of $3 Million goes into a trust fund to be distributed to someone. Charlie seemed pretty angry by this and decides to look into this matter. It seems as if that "someone" is Raymond, Charlie's unknown brother, an autistic savant who lives in a world of his own, resides at the Walbrook Institute. Charlie then kidnaps Raymond and decides to take him on a lust for life trip to the west coast as a threat to get the $3 Million inheritance. Raymond's acts and nagging, including repeated talks of "Abbott & Costello", "Four minutes till Wapner" and refusal to fly on an airline except Qantas drives Charlie insane... and out of his selfish world into a cross-country trek of pure love and understanding that these two both have.—Christopher Howell (Ckhowell75360@aol.com)

When car dealer Charlie Babbitt learns that his estranged father has died, he returns home to Cincinnati, where he discovers that he has an autistic older brother named Raymond and that his father's $3 million fortune is being left to the mental institution in which Raymond lives. Motivated by his father's money, Charlie checks Raymond out of the facility in order to return with him to Los Angeles. The brothers' cross-country trip ends up changing both their lives.—Jwelch5742

In this story we retrace the path of two brothers who meet and get to know each other following a legacy story that led Charlie to "kidnap" his brother from a psychiatric hospital, claiming the amount that his father had not paid him following his death. Raymond, an autistic scholar, and above all, the one who inherited the small fortune, is his brother from whom he was separated too early to know that this imaginary friend he called "Rain man" was him. What is interesting about this film is the link that is created between two very different people. Raymond, being autistic, has difficulty communicating like the others, although most people in his case do not know how to speak at all, moreover, it makes it difficult for him to express his emotions and he is very sensitive to his routine; all characteristics of autism. Later we will see that he also has extraordinary memorization abilities that his brother will not deprive himself of using for his purposes. Charlie works in a car sales company, rather charismatic, he knows how to speak and be heard and has no trouble expressing himself. Throughout their journey, travel the hotel by hotel, the kidnapping quickly becomes an opportunity to create new links destroyed in the past.

Charlie is a hustler. He's been on his own long enough to know how to work people and situations. He finds that the father who threw him out as a teen ager has died. He's left him a now antique convertible and something more important, a previously unknown brother, Raymond. Raymond is autistic, but is able to calculate complicated mathematical problems in his head with great speed and accuracy. Their father has left his fortune to Raymond who doesn't even understand what money is for. Charlie is enraged by what has happened and by his father keeping Raymond's existence from him for his entire life. He kidnaps Raymond from his residential home but then finds that Raymond will only fly Qantas. The two begin a long road trip that will lead them to an understanding of each other.—John Vogel <jlvogel@comcast.net>

Charlie Babbitt (Tom Cruise), a Los Angeles car dealer in his mid-twenties, is in the middle of importing four gray market Lamborghinis. The deal is being threatened by the EPA, and if Charlie cannot meet its requirements, he will lose a significant amount of money. After some quick subterfuge with an employee, Charlie leaves for a weekend trip to Palm Springs with his girlfriend, Susanna (Valeria Golino).

Charlie's trip is canceled by news that his estranged father, Sanford Babbitt, has died. Charlie travels to Cincinnati, Ohio, to settle the estate, where he learns an undisclosed trustee is inheriting $3 million on behalf of an unnamed beneficiary, while all he is to receive is a classic Buick Roadmaster convertible and several prize rose bushes. Eventually he learns the money is being directed to a mental institution, which is the home of his autistic brother, Raymond (Dustin Hoffman), of whose existence Charlie was previously unaware. This leads Charlie to ask the question that permeates the movie: "Why didn't somebody tell me I had a brother?"

Although Raymond has autism, he also has superb recall, albeit usually with little understanding of the subject matter, but has extreme skills in mathematics (in those scenes he merely remembers the answers, and with no understanding of currency.) He is said to be a savant by some doctors. He is frightened by change and adheres to strict routines (for example, his continual repetition of the "Who's on First?" sketch). Except when he is in distress, he shows little emotional expression and avoids eye contact.

Numbed by learning that he has a brother and determined to get what he believes is his fair share of the Babbitt estate, Charlie takes Raymond on what becomes a cross-country car trip (due to Raymond's fear of flying) back to Los Angeles to meet with his attorneys. Charlie intends to start a custody battle in order to get Raymond's doctor, Dr. Gerald R. Bruner (Jerry Molen), to settle out of court for half of Sanford Babbitt's estate so that the mental institution can maintain custody of Raymond. Susanna, disgusted by Charlie's self-centered nature and his attempts at using his brother as a pawn to gain the money, leaves Charlie in Cincinnati and disappears.

During the course of the journey, Charlie learns about Raymond's autism, which he initially believes is not authentic - resulting in his frequent frustration with his brother's antics. He also learns about how his brother came to be separated from his family, as a result of an accident when he was left alone with Charlie when Charlie was a baby. Raymond also sings "I Saw Her Standing There" by The Beatles like he did when Charlie was young, prompting Charlie to realize that Raymond is the protective figure from his childhood, whom he falsely remembered as an imaginary friend named "Rain Man", which was a mispronunciation of "Raymond". Charlie proves to be sometimes shallow and exploitative, as when he learns that Raymond has an excellent memory and takes him to Las Vegas to win money at blackjack by counting cards. However, towards the end of their trip Charlie finds himself becoming protective of Raymond and grows to love him truly.

Charlie finally meets with his attorney to try to get his share of his inheritance, but then decides that he no longer cares about the money and really just wants to have custody of his brother. However, at a meeting with a court-appointed psychiatrist and Dr. Bruner, who is also a friend of Charlie's father and is left in charge of that money, Raymond is unable to decide exactly what he wants. Eventually, the psychiatrist presses Raymond to make the decision, upsetting him and leading Charlie to request that the doctor back off. Raymond is allowed to go back home to Cincinnati. Charlie, who has gained a new brother and mellowed considerably, promises Raymond as he boards an Amtrak train that he will visit in two weeks.
