'Warehouse 13' gets trailer, return date -- EXCLUSIVE

Syfy has a premiere date for the return of Warehouse 13 and its first summer promo too.

Season “4.5” will pick up on April 29 for the show’s final 10 episodes of the season in a new time slot — Mondays at 10 p.m. The schedule shift will give Warehouse 13 a lead-in from Syfy’s new drama Defiance.

Warehouse 13‘s premiere episode, “The Living and the Dead,” picks up where the midseason cliffhanger left off, with Artie (Saul Rubinek) having infected the Warehouse Team – and the world — with the Black Orchid Artifact’s deadly pandemic virus. The team races to stop the spread of the disease while personally battling its symptoms. The premiere also kicks off Polly Walker’s (Caprica, Rome) arc on the show as a historian who may know more about the Warehouse than she lets on. Returning guest stars will include Jaime Murray and Kate Mulgrew.

Here’s an exclusive first look at the back half of the season:
