The film begins at a fashion show, where Chloe Keene (Jessica Alba) takes the catwalk.

She returns home to her boyfriend Toby (Oliver Milburn) and tells him what a great time she had in New York.

After this, she goes to a shoot, where she meets her other boyfriend, Ned (Gary Love), who offers to take her out to a reunion of his former band.

Chloe falls asleep in the car due to pills she has taken, and wakes up when she arrives at the reunion.

At the reunion, she meets Stan (Iain Glen), his wife Rachel (Jeanne Tripplehorn), his deaf daughter Theresa (Mischa Barton), and his brother Gordon (Ewen Bremner), who films the party.

While they are having lunch, Ned's wife Eve (Gina Bellman) arrives, and is rude to her, causing her to cut her hand on a glass.

Using her barefeet to pick up the phone, Chloe answers, and tells him she is trapped in the house that used to be a hotel.

Theresa finds the tapes somewhere, and makes a poster to hand in to the police about Chloe, but they just laugh.

Upstairs, Theresa breaks the window with a chair, and escapes down the side of the house, just as the police arrive.
