In Los Angeles a deadly plague called the 'Pandora' virus is stolen from a high-security installation, and the F.B.I. calls in Agent Alec 'Mac' Mckay to follow up the leads. A trained virologist, he discovers the culprit is one of the world's top researchers. He discovers the man has a safety box in a bank vault and a trap is laid to capture both the doctor and reclaim the virus. Meanwhile, Julie Hayes discovers her do-well brother Scotty has become involved in the plan to rob a bank... The very bank that the F.B.I. is now watching in their bid to reclaim the Pandora virus. An unwilling accomplice, Julie tries to alert the bank staff, unaware that the man she thinks is a bank teller is in fact Mac working undercover. Things go from bad to worse when the errant doctor, looking tense and terrified, arrives with a tall, blond-haired, leather-clad man whom the watching agents identify as St. Joy, the leader of the L.R.A., a well-known doomsday cult. St. Joy wants Pandora. He wants Pandora...
