Six Against the Rock is a thrilling film about an inmate at Alcatraz, Bernie (David Carradine), who decides to break out of the infamous high-security prison. He devises a plan to get the key to the yard and enlists five other inmates to help him carry it out. Once he gets the key to the yard, his plan is to climb over the fence and escape into the real world. Bernie's well devised plan is put to hold though when he and his friends cannot get their hands on the right key for the yard. The five inmates that help out Bernie all desperately want to be free and take Bernie's plan as their own. The six men band together and work their way through the high-security prison in order to finally see the outside world after being locked up for years, and with no intentions of ever getting parole.
