Excellent
I hadn't seen this movie in years, but I always remembered much about it. Especially the acting.
I recently bought it from Amazon and it didn't disappoint. Good Story, great acting.
Especially from Stella Stevens. I know that she's mostly known from the Poseidon Adventure, and yes, she was excellent in that too.
But my personal opinion is that in this film, this was the best acting she ever did. Kudos to her.
