Dr Soboda (Ennio Girolami) is a renegrade scientist who has developed a death ray. He uses it to blow up a train and melt the unfortunate couple getting it on inside a boxcar. Soboda wants millions of dollars from the San Francisco authorities otherwise he will use his death ray again. He indeed does use this at a race track to deadly effect.
Supercop Inspector Ronn (Erik Estrada) is tasked with stopping Soboda. His investigations consists of getting into a string of fights including in a morgue! In fact there are a lot of fights in this, many many fights and many many deaths.
This is a fun 1980s action romp, full of stunts and action scenes and doesn't make a lot of sense. Not a film for character development, much in the way of plot or any logic. But the film is highly enjoyable as a mindless action romp so who cares?
