**SPOILERS** One of the many exploitation movies made in the 1930's about weed pot or marijuana the film "Marihuana" is mostly about a sibling rivalry between two young sisters Berma and Eline who come from one of the towns most upright and blue blood families.
Eline is engaged and to be married to local rich well connected and also blue blood Morgan Stuart while Berma is in love with a local boy who's both poor and out of work Dick Collier. With Eline being her moms favorite Berma rebells by partying and going out with the wild crowd who drink and do pot and have naked sex parties at night.
One Saturday evening after having a wienie roast on the beach the roast turns deadly when one of the girls Joann, Berma's best friend, who was drunk and butt naked runs into the ocean and drowns. Meanwhile back at the beach house the rest of the girls at the party undress and run naked out on the beach skinny dipping into the cold waters with their boyfriends, fully dressed, chasing them. Alone and by themselves both Dick and Berma has a sexual tryst which later results in Berma getting pregnant.
With the news of Joann's tragic death the local pot dealer Tony Sentello tells the young people at the party, who looked like they were in their early twenties at the least, to keep their mouths shut if they don't want to be taken away from their parents and put into a local orphanage.
Dick wanting to get married to Berma and give their expecting child a proper name as well as a family gets a job working for Tony as a drug runner. On Dick's first day on the job he's shot and killed by the police as he picked up some pot from Tony's sidekick Nickie Romero, who's a dead ringer for actor Andy Garcia,on the waterfront. The very day that Dick was shot and killed Eline and Morgan were happily married at the town church.
Giving her baby up for adoption Berma went to work with Tony and Nickie in their pot selling racket and later even went into selling the hard stuff, heroin, which she herself soon got addicted to. Leaving an apartment house after selling some heroin to a desperate woman, who gave up her engagement ring for the dope, Berma sees her Sister Elaine with her husband Morgan and their little girl Gloria. Berma gets this idea to kidnap Gloria and hold her for a ransom of $50,000.00 from her rich parents knowing that both Eline and Morgan wouldn't want this to become public with the person responsible for the kidnapping being a close family member.
Going to get in touch with Morgan to get the ransom money Berma get the startling news from her brother-in-law that Gloria is not his and Eline's real child but she was adopted from an underground baby selling mill and she's really Berma's child that she gave up for adoption some three years ago.In a state of shock and emotionally destroyed Berma realizes that the one thing that she had over her hated sister Eline, a child of her own, she unwittingly gave away to her.
Going back to the apartment hideout where her partners in crime, Tony & Nickie, were holding her daughter Gloria hostage Berma gives herself a "hot Load" injection in her leg. As she enters the apartment Berma finds that the police raided it, and arrested both Tony and Nikie, and rescued Gloria. With the drugs taking affect Brma slowly goes into shock and collapses and overdoses from "the hit" that she just gave herself.
