TV: Warehouse 13 Season 4 "Returns April 29th" Promo

Can America's Best Kept Secret Agents save Artie - and the whole world? Warehouse 13 Season 4 returns Monday April 29th on Syfy.

Warehouse 13 is a U.S. television science fiction series that premiered on July 7, 2009, on the Syfy network.

Executive-produced by Jack Kenny and David Simkins, the dramatic comedy from Universal Media Studios is said to have borrowed much from the American-Canadian horror television series Friday the 13th: The Series (1987–90), and has been described as "part The X-Files, part Raiders of the Lost Ark and part Moonlighting." The series premiere was Syfy's third largest debut to date, garnering 3.5 million viewers. The first six episodes were all among the top ten highest rated series episodes on Syfy. Episode 6, "Burnout", drew 4.4 million viewers, setting the record for Syfy's highest rated show. Season 2 began July 6, 2010. It was renewed October 5, 2010, for a third season of 13 episodes, which began July 11, 2011. It was renewed for a fourth season August 11, 2011, which began July 23, 2012.

Characters from Eureka have crossed over to Warehouse 13 and vice-versa, and actors from Warehouse 13 have crossed over to Alphas.
