When flight attendant Cassie Bowden meets passenger Alex Sokolov, she decides to spend an extravagant, very drunk night with him. But when she wakes up the next morning beside a dead body – and with no memory of what happened – Cassie fights to keep her wits about her long enough to make it back to New York, where more trouble looms.

Cassie follows a surprising paper trail to a suspiciously empty private jet service. Later, a visit from her brother Davey forces Cassie to confront her memories of her "unconventional" childhood.
