Three policemen guard a witness repentant in an abandoned warehouse. Their job is to watch him until the morning when the morning shift will take over, but the witness persuades them that "those who are coming" intend to kill not only him, but all four of them. Their paranoia grows when they find out the witness is familiar with some details from their black pasts which are known only by their close accomplices. They punish each of his stories from the past by beating him up. When the morning comes, the policemen are drunk and confused, and the witness is all covered in blood.
