You are cordially invited to summer on New York State's idyllic Fire Island. Thirty miles of golden sand. No traffic. No tourists. No trash.

The city elite gather here every year, trailing kids, their nannies, wine and seafood imported from Manhattan: hard workers need their playtime.

Take the Parkers and the Weinsteins. Lauren and Jen hold sway on the beach and the tennis court. Their husbands are childhood friends bearing grudges as deep as they are secret.

Their lone single friend, Rachel Woolf, is looking to meet her match, whether he's the new tennis pro – or someone else's husband. She's not picky. And while this season starts out quietly as any other, it soon changes when beneath the boardwalk, a body is found.

No one is claiming to be a good person..But is someone actually capable of murder?
