Luke, Joe and Holly have grow up in a world where an Alien race is master. They live in a camp with a few other "survivors", but when this camp is destroyed they have to flee. They stumble across a secret military base and meet an eccentric scientist called Bretnel. Is he helping them or is he just using them as lab rats? Either way the Aliens are closing in. Will Luke, Joe and Holly have to run again or this time will they be able to stand and fight?
