When unfeasibly rich engineer Sam Prentis loses his genitalia to a rogue Rolls Royce sprocket, he is sold on the idea of a prosthetic phallus by the unfortunately named Richard Edwards, A K A Dick Ed. To inherit a fortune, Richard and Sam's gold-digging wife load a bionic replacement with liquid nitro. It's primed to detonate during aphrodisiac enhanced copulation, but something goes terribly wrong, or right, (depending upon who's looking at it.)
