 The crew of Enterprise have a meeting with the trader D Marr. Unfortunately he is unable to provide them with valuable ores, but knows of a location where these can be obtained. He tells he found an apparently abandoned ship and tried to empty it to make a fortune. But according to D Marr the ship is haunted and he was forced to leave. Enterprise starts looking for the ship anyway. Scans show there really aren t any bio-signs, but after coming on board the crew soon gets the feeling they are not alone.
