Invasion

Cult British sci-fi thriller. After a traffic accident victim's blood is found to be unidentifiable, hospital staff are shocked to hear his claims that he is an escaped prisoner of an alien spaceship. However, his outlandish claims appear less shocking when a spaceship crash lands near the hospital and a force field mysteriously appears around the building.

Dr Mike Vernon (Edward Judd), who is caring for the patient, vows to protect him from the invaders, but the aliens are eager to hunt down their escapee before he betrays their valuable intelligence secrets to the humans.
