Getting away with murder. Seems unlikely, but in the gated community of Avalon it's what's in style. It all starts with Hudson's accidental decapitation. It was a terrible accident. He was drunk and in the middle of a fight with his second wife. They both pressed the garage door button at the same time. The LAPD didn't give it a second thought. Instead of grieving, his wife breathes free air again. She is a rich woman with freedom. The other wives secretly envy her. From the outside, Avalon seems like the ideal place to live; full of rich men and beautiful women. Six couples form a close-knit friendship; the men all golf together, the women all shop together, and their six children all skip school together. But the wives begin to resent feeling like possessions and realize that the men become crueler every day. When more husbands start dying, the so-called "Ladies of the Lake" find themselves under suspicion from the LAPD and their own children. The six children try to uncover their parents' secrets before the handsome Detective Daniels can discover what is truly going on behind closed gates.
