The rescuers discover that Churchill has been severely damaged by fire, yet the three containers bearing the aliens remain intact. The aliens are taken to the European Space Research Centre in London. Prior to an autopsy, the female alien awakens and drains the life force out of a guard. She then escapes the facility and proceeds to drain other humans of their life force, revealing an ability to shape-shift.....
