Light is streaming through the crack beneath the door to the actors' lounge. Actress Kate Sachs steps into the room to turn it off, and her life changes in an instant. A man in a mask is hiding in the shadows and her director lies crumpled in a corner, unconscious. The man attacks her, but stops short of killing her when he hears a noise and runs away. The police arrive and rush her director to the hospital. Then Kate goes home, never suspecting that everything she holds dear is now in jeopardy. But when the man in the mask threatens her family, she fights back, and in a deadly game of cat and mouse, the hunted becomes the hunter.
