Bound and Gagged: A Love Story (1993)

"Not your average insane road movie."

Leslie's husband Steve is a brute and she wants out, at least she thinks she does. Her lover Elizabeth agrees that Steve needs to go away, so they plot his murder. Meanwhile their friend Cliff can't seem to get used to the idea that his wife has left him, and he tries to kill himself. The murder doesn't go as planned, the suicide doesn't go as planned, and Elizabeth, Leslie, and Cliff find themselves on the run from a very angry Steve. Trouble is, Leslie isn't so sure she wants to leave, so Elizabeth is compelled to compel her to accompany them.
