M-Net’s actionX, channel 6 on DStv, is to screen the exclusive new series Threshold which takes viewers on a journey to the Atlantic Ocean.

A team of experts are assembled when the US Navy makes a chilling discovery: an extraterrestrial craft has landed in the mid-Atlantic. Dr Molly Caffrey is a contingency analyst whose job it is to devise response plans for worst-case scenarios including threats to national security.

In a single instant her life changes when one of those plans, Threshold, is activated by Deputy National Security Advisor, J T Baylock. Armed only with her hypothetical strategy to address the appearance of the aliens on Earth, Caffrey now finds herself thrust into the midst of a global crisis.

She hand-picks a team of specialists to prepare for first contact: Dr Nigel Fenway, a disillusioned NASA microbiologist; Lucas Pegg, a brilliant but neurotic physicist; and Cavennaugh, a highly trained covert operative with a mysterious past. Together they decipher the intent of the craft, the fate of the ship's crew and begin preparations for the worst case scenario - an alien invasion.

Threshold will be screened on actionX, channel 6 on DStv on :Wednesdays at 22h00, starting April 26.
