Tech billionaire Slater King (Channing Tatum) meets cocktail waitress Frida (Naomi Ackie) at a fundraising gala and invites her and her friend Jess (Alia Shawkat) to time with him and his friends on his private island.

At first, things are amazing. They enjoying lounging at the pool, drinking champagne and eating food prepared by a chef. But things slowly begin to get strange. And then a little more strange. Even sinister. As Frida begins to question her reality, she'll have to uncover the truth if she wants to make it out of this party alive.
