A hired gunman walks into a hornet's nest of trouble in MONGO'S BACK IN TOWN. Contract killer Mongo Nash (Joe Don Baker) is called home by his ruthless brother Mike (Charles Cioffi), who it is soon learned is under surveillance by the cops for counterfeiting. Things are further complicated when Mike is mysteriously murdered, and Mongo is caught between the law - led by a relentless cop (Golden Globe® and Emmy® Winner* Telly Savalas) - and a rival gang, who thinks Mongo has the counterfeiting plates. With the help of a naïve, small-town girl (Oscar®, Golden Globe® and Emmy® Winner* Sally Field), Mongo begins to unravel a sinister plot with deadly consequences.
