When Chad becomes trapped outside his shuttle in space, Rachel grants her man a dying wish: a wedding via satellite before the oxygen runs out. Paul swings between guilt and euphoria as he weighs up the power to save Chad against a chance with the woman he loves.

To the amazement of everyone, Paul performs well in the saddle when it is Camel Racing Week in Unagatta. After becoming the hope of the town, his triumph coincides Pips mid-life meltdown. He has to make the tough decision of whether to pick sporting glory or bring back the woman who everyone loves.

Paul becomes depressed after solving the mystery of how the Universe will end. Soon after, the local thug challenges him to a duel. In looking for answers, Paul turns to the desert, and Bill ends up teaching him what it means to be a real man.

After recovering from a near fatal encounter with a black swamp toad, Paul thinks he sees the face of God in space. Rachel warns him to keep his mouth shut, as she's seen too many good scientists ruin their careers because of one brief brush with faith. But the team see the phenomenon for themselves and are convinced. Shortly after reporting it to a reputable journal the truth is revealed.

Paul is overwhelmed when his colleagues throw a surprise birthday party for him. But he then receives a call from girl friend Ruth with an exciting surprise - she is in Australia and on her way to the Observatory. How can he get rid of her and live his own life?

Planet of love Venus rises, so hormones in the Observatory rise with it. As a result, Paul's lack of a sex life becomes a focal point and he decides that the best way to shut up his co-workers is to pretend he is having an affair with a girl he met at the pub. The lie gets bigger and bigger as to Paul's surprise, it brings him unexpected bonuses. Rachel seems to become attracted to him and he earns more responsibility at the Observatory.

When Pip throws her back out working her way through the Aboriginal Karma Sutra, Paul is left in charge of the Observatory. His bravado turns to horror when he discovers he must help destroy his childhood hero, an old British satellite called The Perseverance.

After discovering a new planet, Paul makes the choice of naming it 'Unity' to make it a symbol of the togetherness he believes exists between his colleagues. To find out about the discovery, a film crew arrive to interview Paul but he learns how science is no different from real life - as Rachel is instead seduced into the spotlight because beauty sells.
