A woman's body is shown in lantana bushes in suburban bushland.
Leon, a policeman, and Jane have sex in a motel. They part, and Leon and his wife, Sonja, attend Latin dance classes that the recently separated Jane is also taking. Leon does not enjoy the classes.
He savagely beats a drug dealer during an arrest. He has emotional issues but refuses to confront or admit to them, while Sonja sees a therapist, Valerie, who has published a book on her daughter's recent murder. She and her husband, John, barely speak; he refers to their marriage as surviving on their grief. Valerie feels threatened by another patient, Patrick, who is having an affair (with a married man by the name of Nik), forcing her to confront her marital issues.
Jane purposely encounters Leon outside his station, and they have sex despite his reservations. Nik is upset at the relationship because he is friends with her estranged husband, Pete, who wants to return home. Jane pairs with Sonja in the next salsa class, angering Leon, who ends their arrangement, upsetting Jane. She invites Nik for coffee at Paula's behest, his wife with whom she is friendly, and offers him money as they are struggling. Paula now starts disliking Jane.
Valerie, coming home late, crashes. Stranded, she calls John, unsuccessfully. She hails a vehicle but never makes it home. Leon is the investigating detective and searches her office. Surprised at seeing his wife's file, he takes a recording of their sessions, from which he learns that Sonja would not consider an affair a betrayal, but would if Leon didn't tell her. Leon arrives home late, but Sonja is awake. He asks her about her therapy. They discuss their relationship, and he says he just ended an affair but still loves her. Sonja is upset and feels betrayed. Leon sleeps on the couch. In the morning, Sonja says that he will be lucky if she returns home that night.
Leon goes to John's house as he is the main suspect in his wife's disappearance. Leon starts discussing love, marriage and affairs, but lies to John when asked if he ever had an affair. Leon goes to Jane's house after she calls the police. Jane, late one night, saw Nik arrive home and throw something in the bushes. Later, she finds a woman's shoe there. Leon with colleague Claudia arrive and declare the shoe is Valerie's.
The police arrest Nik and he leaves his children with Jane. Police summon Paula for questioning. Neither Nik nor Paula knows that Jane called the police. Although Paula dislikes Jane, she thanks her for minding their children. The police interrogate Nik, but he refuses to answer questions about Valerie, repeatedly asking for Paula. Afterwards, Nik relaxes and talks with Leon and Paula. Valerie had car trouble and hailed Nik. He agreed to take her home but she panicked when he took a shortcut and jumped out, leaving her shoe. Paula goes to Jane's house for her children, where she tells her that Nik is innocent. Jane asks how she knows, and Paula says he told her. Jane asks if she can spend more time with the kids, but Paula forbids it after seeing how Jane went into her house and tidied it. Leon, Paula, Nik, and John go to where Valerie jumped out of the truck. They find her body, as she had fallen down a ravine. Leon listens to the rest of the therapy tape, where his wife says that she still loved him, and he cries.
Leon returns home and sees his wife outside. Jane salsa dances alone, drinking and smoking, and her husband leaves her. Patrick is pained to see his lover, the man seen in his apartment during Leon's investigation, spending time with his wife and their kids. The movie ends with Sonja and Leon dancing seductively. Leon, who found dancing with his wife difficult, now looks into Sonja's eyes and dances, just as she wanted. Sonja struggles to initially return Leon's gaze but does as the movie ends.
