It is 1999 and society has broken down, due to solar flares which turns people into crazies (somehow). Travis (Ronald Marchini) is one of the last cops in the city (and soon the last one), sent by Prescott (Adam West) - with whom he has a hate-hate relationship - to stop slave traders. The raid, against the leather clad warlord Wraith (Chuck Katzakian) and his gang, goes badly and all of Travis' buddies die. He does save Lena (Meg Thayer) from a life on her back however.
As Travis wanders around the broken down city he also picks up two other women, and regularly fights gang members for almost any reason, including to get back his hat! After endless martial arts and gun battles, Wraith descends on Prescott's compound. Travis heads in for a showdown with Wraith... which doesn't actually happen.
The film is rather grubby and seems mostly to contain lost extras from Mad Max ripoffs and late 80s pop videos. The story is nonsense, the action isn't bad, the cheese factor is high. This makes Omega Cop quite a reasonable entry in the post-apocalypse movie genre to be honest.
