Plot

Angela Bridges is a young and beautiful businesswoman who works in a Midtown Manhattan office block and gets stuck working late on Christmas Eve, before leaving to attend a family party. When she reaches the second underground parking level (P2) beneath the office block, she discovers that her car will not start. After receiving assistance from a socially awkward security guard named Thomas Barclay and turning down his offer to spend Christmas with him, she calls for a taxi and waits in the lobby. When the taxi arrives, she discovers she is locked in the lobby and runs back into the parking garage. The taxi leaves without her and the lights soon shut down. Angela, guided by the light on her cell phone, wanders around the deserted parking lot. Thomas, who is revealed to be psychopathic, drugs her with chloroform and takes her to his office.
