 After receiving three new warp injectors by the generous Kreetassans, Enterprise is in need of warp plasma. The Kreetassans give the crew the location of a merchant colony with a deuterium refinery. But after arriving the colonists seem to be very reluctant to trade at all. Enterprise is only able to purchase 200 liters for a ridiculous price and must repair two pumps at the colony. Captain Archer and the crew are beginning to wonder what s going on. The deuterium should have been very profitable, but there s poverty all around. Then Enterprise detects the arrival of a Klingon cruiser.
