Stepmom Summer FlingBeach house boyfriend meets girlfriend's stepmom, and he has seen her before

The story

Summer is here and Gretchen has brought her new boyfriend, Slade, to the family beach house. Her stepmom, Holly, greets him with a smile that makes him stammer. Gretchen's best friend Brittany turns up too, and she asks him a strange question: does he look familiar? Episode 1 is a lot of towels, a lot of laughter and a growing sense that these women have history with this man. Holly keeps her cool. Slade does not. Our desk reports that no rules apply at this house, and the guest list is about to get complicated.

The twist

In episode 2 the memory clicks. Slade and Brittany both remember a night at a club near Montauk, and Holly, it seems, has a past she would like to keep hidden from her husband. She makes Slade a deal: keep it quiet and she will have a surprise for him later. Then a Ferris wheel enters the picture.

Developing story

A secret three people share, a boardwalk full of rides and one very suspicious girlfriend. The paid episodes ask who cracks first.
