The USS Tharsis, an Oberth-class vessel and one of the ships assigned to Peaceforce 5 as a science and survey vessel, has become trapped in a gravity well. The Gorkon arrives to help, but finds the crew's minds twisted - they believe themselves hunters, and the Gorkon crew their prey.
A celebration turns into a murder investigation when a Cardassian diplomat is found dead during the Gorkon's awards after-party. Trapped inside a sabotaged holodeck, will they be able to find the murderer, while keeping themselves and their guests safe?
