Series 1

1. The Black Hole

After an unusual interview, under-achieving, under-confident scientist Paul Hamilton is swept suddenly from his unexciting life and boring girlfriend in London to a thrilling astronomical frontier at the Royal Australian Observatory in the Australian Outback. Can he find the Black Hole and impress his fellow scientists? Can he win the affection of beautiful scientist Rachel, even though she is engaged to astronaut Chad? A world of impossible adventure opens up before him.

2. God Are You Out There?

The age-old clash between religion and science. Paul thinks he sees God in the gullet of a wormhole and becomes determined to publish his beliefs. But as Rachel, the cool cynical and terminally atheist, reminds him, there is no place in science for religion and God did not create the world. But then Pip and Rachel also see the face in the wormhole, and reluctantly agree that Paul may be right and should publish his paper.

3. When You Wish Upon a Star

Paul is overwhelmed by the support and love of his colleagues when they throw a surprise birthday party for him, and for the first time ever feels like a real man. And then he gets a call from girl friend Ruth with her 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?

4. Venus Rising

Venus, the planet of love, is in the ascendant. Hormones and temperatures in the Observatory rise with it, and Paul’s lack of sex life becomes a real focus. He realises the best way to shut up his well-meaning colleagues is to pretend he is having a raging affair with a biker chick he met at the pub - a simple lie that can’t hurt anyone. To Paul’s surprise, it seems to bring him unexpected bonuses. Pip gives him more responsibility at the Observatory, and Rachel seems genuinely attracted to him for the first time ever. So the lie gets bigger and bigger.

5. Unity

Paul discovers a new planet, which he names Unity as a symbol of the togetherness he feels exists with his weird and gifted fellow scientists. A film crew - led by the sleazy Alistair Foster (Craig McLachlan) - arrives to interview Paul and capture the discovery of the new planet, but Paul learns science is no different from real life - beauty sells, and Rachel is seduced into the spotlight.

6. Where Men are Men

Paul solves the mystery of how the Universe will end, but his own demise may come sooner when he is challenged to a duel by the local thug. It is Paul’s High Noon. Paul looks for answers in the desert, and it is Bill who teaches him what it means to be a real man.
