He's taken to the labs of Medtech after being captured by an evil border guard, and they press him into service. It's an easy decision. It seems that the evil frog people have raided a border town and stolen a bunch of fertile women. There are a few genuinely funny scenes where Piper discovers the special properties of his new underwear, but most of the laughs in this movie are at its own expense. Early on the senior Medtech woman tries to excite Piper to get him ready to perform his duties with a recaptured fertile woman.
Nobody looks like they really care, and nothing about the movie seems real.
The best part of the film are the ridiculous inhabitants of Frogtown, who look like mistakes from Planet of the Apes . Late in the movie, a man falls off a high rock after Piper thows his sword at him. He falls down and lands in the clearly visible stunt bag. Not only can you see the thing as he hits it, you can hear the dull thud and whooshing sound. However, it is quite entertaining and would be well enjoyed by a gang of bad movie lovers.
