Dark Star

The spaceship 'Dark Star' is on a deep space mission to clear intergalatic highways. Any unstable planet in the way is destroyed with a huge nuclear bomb.

After 20 years in space, the professionalism of the four crew members has long since disappeared. The endless boredom has had its toll - the ship's computer is now a lot sharper than the crew.

They manage to detonate Bomb#19 to succesfully destroy a planet. But the next Bomb, #20 seems to be developing a mind of its own.
