Young Therese (later played by Elizabeth Olsen) is left in the custody of her aunt Madame Raquin (Jessica Lange) by her father who leaves for Africa. Madame Raquin knows that he will never return and assigns Therese to be the caregiver to her sickly son Camille. Time passes by and Therese gets used to the life of confinement in the Raquin home, caring for Camille (Tom Felton) and eventually surrenders to an arranged and unexciting marriage to him. Then comes an opportunity dor the family to move from Vernon to Paris where Camille gets a clerical job, Madame Raquin rents a shop and sets up their home upstairs. One evening, Camille brings home his old friend Laurent (Oscar Isaac), a dark haired, handsome man, and a new world of excitement and adultery beckons Therese. Laurent and Therese embark on a clandestine and passionate affair that spells doom for Camille as they together hatch a plan to eliminate him.
Everything proceeds according to their plan with Camille out of the way, and the family's well wishers insist upon Therese now marrying Laurent, looking at the misery of the women, of course totally unaware of the sinister plot that led to the situation. Once married, however, the couple is soon consumed by the guilt of their crime and the ominous presence of Camille's shadow in the relationship turns matters bitter. During one such friction, Madame Raquin also learns about the truth and turns antagonistic, albeit she can do little as she is now paralyzed physically.
"In Secret" is an adaptation of the novel Therese Raquin written by Emile Zola, and could have been a tragedy of an epic Shakespearean dimension. The drama noir is accentuated by the dark setting in Paris with a depressing and poorly illuminated shop and house above. Director Charlie Stratton however makes a half hearted attempt to capitalize on the dark setting and the resultant mood with an unconvincing treatment of the psychological tussle with conscience, thus turning the tragedy into a rather soft and mellow climax. Not enough was done to delineate the "blood on the hands" state of the doomed couple that could have emphasized the extreme consequence of the once passionate relationship. Elizabeth Olsen and Oscar Isaac do their bit, but Jessica Lange is the showstopper here with a powerful portrayal of Madame Raquin, a controlling matriarch with firm hands on the reins of her family.
