Ralph is turning 45, and the only gift he wants is his ex-wife. Gemma, his trophy girlfriend, won't let anything ruin her plans for an engagement. Sarah, the ex-wife, has agreed to attend Ralph's party, with her new man in tow. And Jack, her partner, will stop at nothing to keep Sarah out of her ex-husband's clutches. It's a celebration like no other. The whole extended family in a villa on the beautiful Amalfi coast. But by the end of the trip, two people will be dead. At this birthday party to remember, will anybody unwrap the truth...? Two weeks. Four guests. One party to die for.
