The relationships of four couples unravel after the discovery of a young woman's body in Lantana bush in suburban Sydney.

Leon Zat: [the morning after Leon admitted having an affair] I fucked up, all right? People fuck up.
Sonja Zat: Really? Well, I don't. You know what's so easy, Leon? It's so easy to go out and find somebody. You know what's hard? What's hard is not to.
Leon Zat: [Leon has chest pains after having sex with Jane] I get this pain in my chest sometimes.
Jane O'May: You know, you really should have told me that you have a weak heart.
Leon Zat: I don't.
Jane O'May: It's because I don't want to have an affair with...

Leon Zat: I tell my wife everything.
John Knox: That suprises me.
Leon Zat: Why?
John Knox: Most men hold something back.
