Sci-fi drama Continuum will end its run in 2015 with a six-episode fourth season, which will wrap the show’s story. The series has been renewed both by its original channel, Canada’s Showtime, and Syfy, which has been carrying it in the U.S.

Continuum, a futuristic police drama starring Rachel Nichols as a cop from the future who finds herself trapped in present day Vancouver, started with a 10-episode first season, which was followed by 13-episode second and third seasons. Co-starring on the series, produced by Reunion Pictures in association with Shaw Media, are Victor Webster and Erik Knudsen.

Syfy acquired Continuum following its strong launch in Canada, with the premiere scoring Showcase’s highest-rated episodic telecast ever with 900,000 total viewers and 427,000 adults 25-54.
