Generation Ship

A giant space ship leaves Earth to colonise a distant planet. After 250 years and several generations of the community of 18,000 people, the planet is near. Of course, it's all going to go as planned, isn't it? Come on, you all know it isn't. An autocratic Governor of the community, a ship's captain who seems to be nowhere, a security officer trying to climb to power, a dedicated project scientist trying to be heard, and a bunch of misfits who have won the lottery of being alive at the final approach. But what if the planet has other plans? And remember HAL from that other movie? Yeah, don't worry about that.
