Threshold (Season 1)

Watch Threshold (2005) online — a CBS science fiction drama produced by Brannon Braga and David S. Goyer. A freighter at sea encounters something unidentified overhead; by morning, part of the crew is dead in ways the medical examiner cannot categorise. The survivors seem fine. They are not fine.

The government activates a classified protocol and hands control to contingency analyst Dr. Molly Caffrey, played by Carla Gugino. Her assembled team includes Brent Spiner and Peter Dinklage in an early role, years before Westeros. What makes the show stick is its framing: this is not a war-of-the-worlds scenario, it is closer to a slow infection — and the investigators cannot always tell who is already compromised. CBS cancelled it mid-run; nine episodes aired and four more were filmed but never broadcast, all available here. Stream Threshold online on iFILM.
