context: AngÃ©lique (Audrey Tautou) purchases a single pink rose at a flower shop to be delivered to her lover, Dr. LoÃ¯c Le Garrec (Samuel Le Bihan). AngÃ©lique is a successful art student. In between creating her art projects, she works part-time at a cafe and house sits for a wealthy vacationing family. AngÃ©lique's friend David (ClÃ©ment Sibony) disapproves of AngÃ©lique's affair with LoÃ¯c, who is married, but AngÃ©lique insists that LoÃ¯c will leave his wife for her.
  When LoÃ¯c's wife, Rachel (Isabelle CarrÃ©), has a miscarriage, the pair separate and AngÃ©lique prepares to leave with LoÃ¯c on a romantic getaway to Florence, Italy. However, LoÃ¯c doesn't meet AngÃ©lique at the airport, having chosen to mend things with his wife. This throws AngÃ©lique into a self-destructive cycle of clinical depression, losing her job and scholarship. While watching the news one night, she learns that LoÃ¯c has been arrested for assaulting one of his patients, Sonia Jasmin (Nathalie Krebs). She goes to Sonia's house to convince her to drop the charges, and in the ensuing scuffle, Sonia has a heart attack and dies. AngÃ©lique steals from the house to make it look like a robbery. AngÃ©lique thinks this will win LoÃ¯c back, but instead he's arrested for Sonia's murder, and embraces his wife as he is dragged away. AngÃ©lique returns home, turns on the gas and lies down on the floor.
  At this point the film rewinds to the opening scene when AngÃ©lique bought the pink rose. This time the film follows the delivery boy and the subsequent events play out from LoÃ¯c's viewpoint.
  LoÃ¯c receives the pink rose and assumes that his wife sent it to him. It is revealed that LoÃ¯c barely knows AngÃ©lique, and they cross paths only because AngÃ©lique is house sitting LoÃ¯c and Rachel's neighbor's house. LoÃ¯c receives AngÃ©lique's gifts and messages, but doesn't know who sent them. It is revealed that Rachel's miscarriage was caused by "someone" running her down with a moped; earlier in the film, AngÃ©lique is shown after an "accident" which ruined her friend's moped and injured her arm. LoÃ¯c comes to believe that his stalker is Sonia; he physically attacks her and she presses charges for assault. After she dies of a heart attack, LoÃ¯c is arrested as the prime suspect for her murder. At his arrest, Rachel tells the police that he was with her on the night of the death, which clears him of all charges.
  That night, LoÃ¯c sees an ambulance pull up to his neighbor's house. AngÃ©lique has just tried to commit suicide, and as a doctor, LoÃ¯c performs mouth-to-mouth resuscitation which causes her to regain consciousness. Now aware of AngÃ©lique, he considers the possibility that she is his stalker. LoÃ¯c explores the house that AngÃ©lique was house-sitting, and finds a life-sized garbage mosaic of himself. AngÃ©lique and LoÃ¯c have a final confrontation, where he declares that they never had nor will ever have a relationship, and AngÃ©lique strikes him over the head with a brass figurine. She is arrested, diagnosed with erotomania and remanded to a mental institution. Rachel stands by her husband while he recovers from his injuries, with a scene showing the couple in a house filled with their children as LoÃ¯c hobbles around on a cane.
  Five years later, AngÃ©lique is released from the mental institution. Her therapist praises her progress and tells her, "If you keep taking your medication, you will be fine." However, when the cleaning man is clearing AngÃ©lique's room, he discovers her pills have been glued to the wall behind the wardrobe in a mosaic of LoÃ¯c, thus showing that AngÃ©lique has never taken her medication. The film then ends with a quotation from a real erotomaniac, "Though my love is insane, my reason relieves the pain of the heart, telling me to be patient and not lose hope," displayed on the screen.
