Last time we told you how the Supergirls did General Hospital. This time, the girls really take the plunge by invading a United States Navy submarine.

Raven and her college classmates undertake a school project with the Navy Department. Raven wants to get extra credit; her girlfriends just want go et laid!

An actual sub (or a great set) is the décor for this romp beneath the sea. Instead of extra credit, these girls from their own U.S.O. party to keep the crew’s morale at full flag.

Just like the Navy however, this film is pretty routine. Basic performances in both acting and sex make for a slow-paced production that’s even boring at times. There is no sexual enthusiasm at all from the women. I think it may be time for the supergirls to shape up or ship out.
