JUNGLE WARRIORS 1984 (SYNERGY)

A plane carrying several models is shot down over the jungle and they are taken captive by a drug lord's army. The women are captured, tortured, sexually abused and then they finally escape and kill many of the bad guys with machine guns.
The casting of Paul Smith and Sybil Danning as a very bizarre brother sister duo is perfect, and Danning does a good job with what she has to work with. Her interrogation of the women is always fun to watch.
The rest of the cast is also B movie heaven with Alex Cord, Dana Elcar, Marjoe Gortner, Woody Strode, John Vernon and Baroness Van Pallandt Nina.
If you like action films you'll probably enjoy this as well.
