Haydon Cliff Police Detectives Sean Callahan and Andy Mantegna are investigating the second murder of an elderly lady strangled with socks. They really hope they don't have a serial killer on their hands, because Haydon Cliff hasn't recovered fully from the homeless serial killer of a few months before. Soon they begin to connect the killings in a strange way to a weekly bingo game. When more murders occur just as their own personal partnership heats up, they can no longer deny the killer is one and the same for all the victims. But the killings might be even more sinister than first thought. It's up to Sean and Andy to figure it out before their detective team is split up just when they don't want to be parted.
