Film is forever.
It's dubbed but the synch isn't too bad, and it's also in Scope. K2 is Gary Hamilton, framed, imprisoned, and workin' on a chain gang. Gary comes to town and the party starts. He takes advantage of a system of catacombs only he knows about, but unfortunately the bulk of the firefight takes place during a sandstorm in the dark. Marcella Michelangeli is the babe playing Mrs. Ackenbar.
