THRESHOLD is a suspenseful drama about a team of experts who are assembled when the U.S. Navy makes a chilling discovery: an extra terrestrial craft has landed in the mid-Atlantic ocean. Dr. Molly Anne Caffrey ( Carla Gugino ) is a government contingency analyst whose job is to devise response plans for worst-case scenarios. In a single instant, her life changes when one of those plans--THRESHOLD--is activated by Deputy National Security Advisor J.T. Baylock ( Charles S. Dutton ). Armed only with her hypothetical strategy to address the appearance of aliens on earth, Caffrey now finds herself thrust in the midst of a global crisis. She hand-picks a team of eclectic specialists to prepare for first contact: Dr. Nigel Fenway ( Brent Spiner ), a disillusioned NASA microbiologist; Lucas Pegg ( Rob Benedict ), a brilliant but neurotic physicist; Arthur Ramsey ( Peter Dinklage ), an expert in languages and mathematics; and Cavennaugh ( Brian Van Holt ), a highly trained covert operative with a mysterious past. Together, they decipher the intention of the craft, the fate of the ship's crew and begin preparations for the possibility of a crisis situation--an alien invasion.
