On Christmas Eve, Angela Bridges, a young woman, gets trapped in a public parking lot. At first, it seems that this is a minor problem with power supply caused by the festivities, but later she realizes that she has become the victim of a maniac-guard, who has decided to celebrate Christmas in his own way. Now she has an unequal battle with the armed and well-trained man, in which victory would be clearly not on her side. But who knows, maybe fear will give her courage and strength to resist the attacker.
