The Interview (2000)

Eddie Fleming is hauled from his bed one morning by armed police, taken into an interview room and interrogated for hours. At first he seems entirely sympathetic: not only is his treatment harsh for a simple car theft investigation but he is unemployed and has recently lost his wife and home. However, it is revealed that there is more at stake, and that the police are actually hunting for a serial killer. Eddie could be an innocent victim or a subtle and dangerous killer. Meanwhile, the detective himself is being investigated by police internal affairs, and may be overzealous or even crooked.
