Violent Zone (1989)

In a place where there are no boundaries, and time has no meaning, a handpicked team of professionals set out on a multimillion dollar mission of rescue. A wealthy businessman uses a good deal of his fortune to rescue his Vietnam veteran son from the Cambodian P.O.W. camp where he is imprisoned. After assembling an elite force of ex-soldiers and journalists to carry out the mission, he accompanies them to Cambodia, where a rehash of Vietnam is set to occur.
