Wedlock aka Deadlock (1991)
Frank (Rutger Hauer) has been convicted of stealing millions of dollars of diamonds which have not been recovered. In his experimental uni-sex prison, each inmate has an unknown partner; when the two are separated by more than 100 yards, an explosive collar kills both inmates. Frank and his female partner escape and head for the money, but they are hotly pursued by his double-crossing colleagues.
The full movie is available on youtube, in one video. I didn’t see it yet, but from the reviews, it’s an entertaining b-movie.
With Rutger Hauer and Mimi Rogers (anecdote: she was the first wife of Tom Cruise in 87-90)
