The crew explores a jungle planet that's been turned into a hunting ground by a race of stalkers called the Eska. They hunt indigenous creatures for recreation, one of which contacts Archer as a shadowy woman he imagined as a child. 

After hearing of a supposedly haunted alien ship on a desolate planet, Archer decides to cannibalize the wreck to replenish Enterprise's supplies and discovers the vessel is inhabited after all. While exploring the ship, the Enterprise crew encounters some ghostly apparitions and an alien race surviving despite insurmountable odds. Trip helps repair their derelict vessel and is befriended by Liana, an attractive humanoid alien who develops feelings for him.
