The guests are arriving, and the celebrations are starting. But there's something strange about this wedding...

Frank Szatowski hasn't seen his daughter Maggie in years, and it breaks his heart every day. So when she calls him out of the blue, to tell him that she's getting married and he's invited, Frank is overjoyed.

Maggie is marrying into one of the richest families in the country, and Frank finds himself overwhelmed by the social circle she now moves in. He'll do anything to reconnect, though, and arrives at their New Hampshire estate ready to bond however he can with Maggie's in-laws.

But as the wedding weekend gets underway, it becomes clear to Frank that although they have spared no expense, there's something strange about Maggie's fiancé. And maybe Frank shouldn't be celebrating just yet...
