Summary
A joint British-American space mission to investigate Halley's Comet discovers a derelict alien craft harboring three humanoid bodies in suspended animation. When the dormant beings are brought back to Earth, they awaken as energy-draining vampires whose touch reduces victims to desiccated husks, triggering a catastrophic outbreak across London as a surviving astronaut and military investigators race to stop them.
