I’m looking for an old b-movie, I’ve seen as a rerun on TV most likely from the 70’s or 80’s. I don’t remember any of the actors, but basically the structure of the story is as follows:
- people are partying on a boat
- the boat breaks down
- most of the passengers leave the boat to look for help
4 passengers arrive at a place (possibly South American?) where they encounter rebels/terrorists who massacre a bunch of locals and are take hostage - one female passenger gets molested but left for dead after she fights back
Some more details that I can remember:
- there’s like a corrupt military man who tries to cut a deal with the rebels/terrorists
- the boat captain who’s ex-military leads the rescue, together with the escaped female passenger (I think).
