While beaming down to the planet Gideon, Captain Kirk finds himself still in the transporter room. He can find no one on the ship, now apparently abandoned by the entire crew. He does find one other occupant on the Enterprise, a beautiful young woman, Odona, who does not know how she got there. Back on the real Enterprise, Spock tries to deal with Gideon’s representatives who claim that Kirk never arrived and claim no knowledge of his whereabouts. Soon, Odona falls deathly ill, which is exactly what the leaders of Gideon were hoping for. Spock soon realizes that there is problem with the beam down coordinates they were provided.
