It was the perfect romantic honeymoon. Until her husband disappeared.

It was supposed to be the happiest time of their lives. But for newlywed Stella, the dream honeymoon has turned into a nightmare overnight. Her perfect husband, Austin, has vanished without a trace.

Alone in Venice, Stella frantically searches for him. But as fear turns into confusion, she finds herself questioning everything she knows about the man she married.

When Stella becomes convinced someone is following her, panic sets in.

As hours turn into days and clues start to unravel dark secrets, a terrified Stella can't help but ask herself: is her husband who she thought he was at all?
