When American PKD researcher Tom Mordley comes to St John's Hospital in London, conscientious Lauren Anderson cannot help herself from falling under the charm of the passionate, charismatic scientist and the invention he has come to test on her patients: a seemingly miraculous drug called Cyberon. However, her doubts about Doctor Mordley's discovery prove justified when all the patients Cyberon was tested on begin to have visions of silvery android-like creatures and other strange experiences, and even moreso when she discovers that Tom Mordley himself, though perfectly healthy, is addicted to Cyberon and regularly injects himself with it. She must figure out what "Cyberon" truly is, and what it wants, before she finds herself succumbing to its otherwordly allure as well.
