Captain Pirk is stranded on Earth in the 21st Century. Realising that history has been changed, he attempts to change it back by making himself the Earth's emperor. Drunk with power he wages war on all alien life.
This is a parody of Star Trek (various series) with elements of Babylon 5 and Stargate mixed in. The plot is clever and the humour is well conceived, but it's spoilt by poor acting. The characters are all wooden and interchangeable. If you want to see a good Star Trek parody watch Star Trek XXX instead.
