Locked consists of five main characters. A man, a woman named Candy, a cat, a bird, and the voice of a woman on the phone. All characters have one thing in common; all are enclosed within their space, some more literally than others. There is a frenetic pace of disconnected sound and imagery in the film providing a sense of disengagement and isolation in each character. Towards the end, there is some crossover, so much so that Candy opens the door to leave.
