The Commander's madness is a subject no one dares comment on even though his latest order has the Star Runner flying back towards the wormhole. Pancha and Sheng try to work out a way to combine their hectic schedules with time for love. Mara is stood down causing Lillian to confront Cyriax who collapses in a fit of alien convulsions.

The only way to save the deteriorating Cyriax is to send him back to Earth. But who will go with him? Volunteers are called for before Acting Commander Steve makes his decision; Tane and Mara. Leonella has other ideas though. If Tane is going, so is she!
