Tricia Helfer (“Battlestar Galactica”) is set to star in Syfy’s new original event series “Ascension.” Created by executive producer and showrunner Philip Levens (“Smallville”), the six-hour drama tells the story of people sent by the US government into space to populate a new world.

The synopsis reads:

In 1963 the U.S. government launched a covert space mission sending hundreds of men, women, and children on a century-long voyage aboard the starship Ascension to populate a new world.

Nearly 50 years into the journey, as they approach the point of no return, the mysterious murder of a young woman causes the ship’s population to question the true nature of their mission.

Helfer plays Viondra Denniger, the beautiful and conniving, very dangerous, wife of the Ascension’s captain, a status that allows her to have great power and privilege over everyone as the ship’s Chief Steward. “Ascension” is slated to premiere in November.
