This time the Gingerdead Man somehow manages to bust out of prison (again, wait, didn't he just die...) go back in time to the 1970's, and torment a bunch of idiots at a roller rink, all while spoofing a bunch of other, better films and TV shows in the process. Sadly, it is...not as fun as it might sound.
