Intro. A young man named Eric discovers a suitcase with three serums that can alter a person's size. He has the freedom to use these serums without any limitations or consequences. The green serum will grow anyone to 50 feet tall and the red serum will shrink anyone to 2 inches tall. The purple serum will reverse the effects of the other two serums.
