The pilot (Renn) sets out for town looking for an Earth woman named Annie Nilssen.
Annie is a local schoolteacher who has recently broken up with her boyfriend, Sheriff Jack Logan.
When she wakes the next day he gives her an egg-shaped supplement and tries to explain to her about how his world had died and why his people needed Earth women - to repopulate themselves.
When his ship is found to be destroyed by a lightning storm they must continue on to the nearest mountaintop to try and connect with his mothership.
They barely make it in time to a mountain where the baby's psychic cry has alerted the mothership to come for them.
