Set in 1860s Paris, In Secret tells the fictional tale of young and sexually repressed Therese Raquin (Olsen) who is married off to her sickly and unpassionate cousin, Camille (Felton). Camille shrugs off Therese's every advance to further their anemic marriage, even on their wedding night. However, Camille's childhood friend and painter Laurent (Isaac) comes to stay with the couple and proves himself to be a far more engaging companion than the frosty Camille.

Faced with a lifetime with an unsatisfying relationship, Therese makes the decision to embark on an illicit and impassioned affair with the sensual painter behind the back of her husband and her domineering aunt, Madame Raquin (Lange). The pair decide that they want to be together unimpeded and make a pact to elope after doing away with Camille on a boat trip. However, their romance after the murder becomes tainted with guilt and the ever-increasing suspicion of Madame Raquin, forcing the couple to confront their sins head on.
