Overview
Lock Up is a 1989 American prison action film directed by John Flynn. It stars Sylvester Stallone, Donald Sutherland, Tom Sizemore, and John Amos. It was released in the United States on August 4, 1989.
Stallone later said it was "Not a film that was produced and performed with enough maturity to really make a significant impact on the audience or my career. And that's the truth".
Plot
Frank Leone, a mechanic in Hoboken, New Jersey, is a model prisoner nearing the end of his sentence in Norwood, a low-security prison. He occasionally spends time outside prison on furlough fixing cars, playing American football and seeing his girlfriend Melissa.
While sleeping in his cell, guards arrive and forcibly take Leone to the brutal maximum-security Gateway Prison run by Warden Drumgoole. Drumgoole explains that he arranged this in retaliation for an incident in which Leone escaped from Drumgoole's previous post, Treadmore Prison, and informed the press about Drumgoole's treatment of his prisoners, after Drumgoole refused to allow Leone a one-hour furlough to visit his dying mentor. Not only did this incident result in five years in minimum security being added to Leone's sentence, but in Drumgoole's transfer to Gateway, a negative mark on his job record.
