About the show:

In the vein of past Syfy mini-series such as Taken, Alice, Tin Man and Battlestar Galactica, ASCENSION is a six-hour event set to debut on December 15.

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, a mysterious murder of a young woman causes the ship's population to question the true nature of their mission.

Tricia Helfer - known and loved by million as Cylon Number Six in Battlestar Galactica- is part of the cast. She will play Viondra Denniger, a beautiful, manipulative and dangerous POWER BROKER on the Ascension.

Brian Van Holt - star of COUGAR TOWN and The Bridge - will play William Denninger, captain of the ship and Viondra's husband. A natural leader, William quickly rose through the ranks after playing a heroic role in a fire early in the spacecraft's voyage. While his professional life is solid, William's marriage to Viondra is anything but.

Andrea Roth, star of Rescue Me, will play Juliet Bryce, head doctor of the Ascension. Her relationship with her daughter, Nora (played by Jacqueline Byers) is difficult and strained. Nora, for her part, is a young woman under intense pressure to follow in the family's footsteps of being a doctor despite her own dreams.

Rounding out the cast are Brandon P. Bell as First Officer Oren Gault, who was born on the lower decks of the ship to maintenance workers and must investigate the aforementioned murder; Tiffany Lonsdale as Chief Astronomer Emily Vanderhaus, the older sister of the murder victim; and PJ Boudousque (Pretty Little Liars) as one of the ship's maintenance workers.

ASCENSION is created and written by Philip Levens (Smallville), who will also serve as Executive Producer and Showrunner.
