In disgrace after a badly handled arrest in New Orleans, Sergeant Lloyd Hopkins is assigned as a liaison officer to an FBI investigation into a series of diabolical and clever bank robberies. Three men have done their they choose bank managers who are having affairs, kidnap their girlfriends, and force the managers to open the banks early. When the bank robbers turn violent, Hopkins finds himself with a bit of information he would rather not have-information about police corruption that reaches into the office of his sworn enemy Fred Gaffney, head of the Internal Affairs Division.
