The Groundstar Conspiracy on AllMovie

Filmed in Canada, The Groundstar Conspiracy was adapted from L.P. Davies' novel The Alien. Michael Sarrazin plays a research scientist who is the sole survivor when his secret laboratory in Vancouver is destroyed by an explosion. Assuming that Sarrazin has engineered the explosion so that he can escape with vital space-program secrets, the government dispatches special-agent George Peppard to track down the fugitive scientist. Sarrazin can remember nothing that happened before the tragedy, but Peppard doesn't buy this story. Only when it becomes obvious that Sarrazin has been targeted for assassination by Persons Unknown does Peppard believe in Sarrazin's innocence, and that a sinister conspiracy may be at the bottom of this whole affair. Christine Belford co-stars as a reluctant cohort of Sarrazin's, though she may not be all that she seems either. Groundstar Conspiracy was produced by the Hal Roach company.
