Lucas (Sam Worthington), a former soldier, is in a club looking for Ella Hatto (Odeya Rush). She is attending boarding school in Switzerland. Ella sees Lucas watching her and thinks he has been hired by her father to protect her. Unknown to Ella, her father was preparing to tell the FBI about Richard Addison's (Allen Leech) illegal operations and also stole 25 million dollars from him.
