Watch An Exclusive Clip Of The 'Helix' Finale

"Helix" Season 1 will end on Friday, and the final hour will be a countdown to avert global disaster.

The Syfy show follows a team of scientists from the Center for Disease Control and Prevention who investigate a disease breakout in the Arctic. In the exclusive clip of the "Helix" finale, Major Sergio Balleseros (Mark Ghanime) is willing to give up the virus and cure for the list and locations of the Inuit children who were abducted and given up for adoption.

Syfy describes the episode: "Together, Alan and Walker must battle The Scythe, but their real enemy might be closer than they’d ever imagined."

Early in the season, HuffPost TV critic Maureen Ryan reviewed "Helix" and wrote, "'Helix' developed a solid momentum as it went along, and putting frightened people in confined quarters with an enemy that can only be seen on a microscope is a recipe for many different kinds of chaos."

Catch the "Helix" Season 1 finale on Friday at 10 p.m. EDT on March 28 on Syfy.
