Brief synopsis of Threshold - The Complete Series
When the U.S. Navy discovers an alien spacecraft in the Atlantic Ocean, National Security Adviser J.T. Baylock (Charles S. Dutton) turns to contingency specialist Dr. Molly Anne Caffrey (Carla Gugino), who quickly recruits a highly skilled investigative team - microbiologist Nigel Fenway (Brent Spiner), physicist Lucas Pegg (Rob Benedict), mathematician and linguist Arthur Ramsey (Peter Dinklage), and covert operative Sean Cavennaugh (Brian Van Holt)- to prepare for the worst case scenario: a possible alien invasion.
