Introduction
The Enterprise is making a supply run to the penal colony on Tantalus V. An apparently dangerous, violent prisoner manages to stowaway onboard. However, when he is captured, he claims to be one of the colonies administrators and that the chief administrator is performing horrible experiments on the minds of his prisoners.
Suddenly, the office Christmas party doesn't sound so bad...
