The Polaris Cadets are in trouble for an accumulation of minor infractions so for a period of 31 days they are assigned to what is supposed to be a tedious Cargo detail as punishment. But on their first run they find a part of their cargo to be alive. The Polaris crew is assigned to take a chimpanzee to a zoo at Venusport, and the chimp proceeds to make monkeys out of the Cadets. (The chimp is J. Fred Muggs, then a regular feature on the old "Today" television show.)
