Lock Up Synopsis & Summary

Sylvester Stallone is a tough but essentially decent convict in a relatively humane prison. He's on such good terms with the authorities that he's occasionally allowed a weekend furlough. This idyllic situation ends abruptly when he's transferred to a nasty prison run by sadistic warden Donald Sutherland (remember way back when Sutherland played good guys and Stallone played secondary hoodlums?) Harboring a grudge against Sly over an unfortunate incident at another prison, Sutherland does everything he can to make Stallone's term a Hell on Earth. But in the end, it is Sutherland who is Stallone's prisoner--and, since Sly's name comes first on the credits, it is Sutherland who blubberingly confesses to a string of crimes perpetrated on the helpless inmates. - Hal Erickson, All Movie Guide
