The Gray Brigade is a story of a man’s life in his Golden Years. After his wife dies, his family puts him in a retirement home in Cincinnati, and he makes friends with other retired men. One is a retired police officer, and with the help of a few friends, they set about creating their own style of vigilante justice by feeding criminal activity to a police detective who handles taking down the criminals.

After his wife’s death, Gary Gray’s children place him in a rest home. He is presented with a new laptop for a birthday present from his daughter and her husband. Gary befriends an 80-year-old patient that used to be a police detective. Gary uncovers a plot to raid a house and tells his detective friend about it. They pass the information on to the police and a successful raid ensues. Problems develop when one of the college students arrested turns out to be the son of a crime boss. They have to protect themselves from a crooked police detective and hit men that come to the rest home looking for a person with a computer.
