WAREHOUSE 13
Syfy, 10:00 p.m. ET
SEASON PREMIERE: Last season’s cliffhanger ended with an evilly-possessed Artie (Saul Rubinek) unleashing a plague upon the world. This new season begins with one pair of warehouse agents setting out to save the world, with the other trying to save Artie – from himself. Along for the entertaining ride? Two genre favorites as guest stars: James Marsters (pictured) from Buffy the Vampire Slayer and Smallville, and Polly Walker from Caprica and Rome.
