Colonel Stella Holmes (Louise Marleau) is investigating for the US government, enlisting the help of police man (and only survivor of the earlier gore fest) Tony Aris (Marino Masé). After some experiments in the lab (including blowing up a rat) they think the eggs and the goo have an extraterrestrial origin... from Mars to be exact. Holmes tracks down ex-astronaut Hubbard (Ian McCulloch) who went off the rails following his mission. He indeed did see the eggs on Mars though his fellow astronaut Hamilton (Siegfried Rauch) denied there was anything there. Pity he died in a plane crash... or did he?
Complete nonsense of course, obviously influenced by Alien though not a complete rip-off. A fun film if approached in the right way, and that right way is to have a laugh at the ridiculous alien monster and exploding bellies. Entertaining rubbish. The film was apparently funded by Columbian drug barons, perfect!
