It has been some time since Philippe was continuing his father's research but the Delambre family is still into the transporting business. Henri and his son Martin work now with the matter transmitter that is seemingly a bit more successful then the versions of their relatives. A transmitter in London receives people who wish to transport from Montreal where their labs are stationed, but not everything is working as it should.
The police are onto things that don't seem quite right at the Delambre estate and vow to find out the truth. In the meantime though, young Martin has found the woman of his dreams, Patricia Staley and takes her as his wife. When he brings her to the lab, the police are even more on the Delambre's case because Patricia is actually an escape mental patient on the run.
As Henri and Martin try to keep things under control, Patricia not only finds the transmission work but also mutated remains of failed transmissions that scare her beyond belief. They try to convince her that it is only her imagination, but it's too real for that. Now things have simply gotten quite silly.
This is another sequel which kind of picks up where Curse Of The Fly left off, but it just goes to pieces from there. While it's nice to see that filmmakers kept it in the family with the Delambres still being the main focus; the film itself is just full of nonsense and takes away from what made The Fly what it is. No longer is it about the mutations or failed experiments, but merely running from the police and keeping them in the dark about things.
It just isn't enjoyable anymore. The films are each shown in 2.35:1 Anamorphic Widescreen and look pretty good for their age.
