Release Message:  The Doctor (Tom Baker), having found a gateway, is having a time with Gundans, robot soldiers programmed to kill.

Description:  Three humorless men from a damaged bulk freighter find the TARDIS. Wearily, Romana returns with them to appraise the situation of their damaged ship but, because she's a time sensitive, winds up as a living navigational component to replace their time-sensitive Tharil (lion-man) who escaped. Meanwhile the Doctor, having found a gateway, is having a time with Gundans, robot soldiers programmed to kill.
