Professor Carter is taken aboard the alien’s ship, whilst one of the aliens stays aboard the Space Force for the journey to the mothership. Carter discovers the aliens are from Alpha Centauri and have travelled to Jupiter in less than one year. The crew arrive at the mothership and are assigned quarters. A holographic image of one of the aliens, named Jenny, informs the crew that men are used as slaves on the alien’s homeworld, with only a select few used for breeding purposes. Chipper begins to fall in love with Jenny. The crew are taken to meet the mothership’s commander, who orders Chipper to be taken for interrogation.
