Nerdy Hobart Moore is kidnapped by three women, and brought to a house occupied by Gertie, a morbidly obese nymphomaniac. Hobart is more interested in making sure his tropical fish are being fed, than in any of the women.

A skinny, virginal mechanic is taken into erotic captivity by three lovely nymphs who decide to give him an enlightening course in sex education. Their goal: to transform a naive nerd into a sexual dynamo for the voluptuous Gerttie.
