In Set Up, Christy Chung plays a writer who gets lasik surgery. The operation leaves her with temporary blindness, and while she is recuperating at her new house, a trio of criminals (led by Roy Cheung) hiding out from a robbery storm in and kill everyone in the house except for Christy. As her sight slowly returns, Christy must play a deadly game of cat-and-mouse with the crooks in order to stay alive long enough until the cops show up.
