Incredible sci-fi kung fu mayhem. The Earth comes under attack from an army of monsters led by Princess Dragon Mum (Terry Liu) who wants to rule the world and make mankind her slaves. Normal weapons (well fists and pistols anyway) are useless against the monsters, however at a secret science base led by the Professor (Hsieh Wang) he converts Rayma (Danny Lee) into Inframan.
Inframan is a bio-electronical marvel who is powered by the sun (although still seems to be able to fight in the dark). He manages to turn the tide of the fight against the Princess and her army. However the Princess isn't finished yet and has plenty of diabolical plans...
Many highly entertaining fights involving people in rubber suits follow. The film is remarkable cheese though plot wise is a bit basic (not that that really matters too much in this kind of film). The film includes many strange scenes to enjoy, one of the best being the scene after the Professor is captured by the monsters and is taken to their lair in a speed boat, flanked by two rubber suited monsters!
