“Elements”
When a sculpture is stolen thanks to a Native American artifact that allowed the thief to walk through the steel walls of a vault, Pete (Eddie McClintock) and Myka (Joanne Kelly) are sent to New York City to investigate.  The hunt for the truth eventually leads them to the discovery of a sacred place—and they’ll do all they can to protect it.

Guest Stars: Joe Flanigan, James Naughton
Air Date: August 4, 2009 @ 9 PM

Flanigan plays Jeffrey Weaver, a wealthy man “whose charm captures Myka’s interest, but he finds himself under Pete and Myka’s scrutiny when a sculpture on which he bid, vanishes in an impossible heist,” the network said.

Warehouse 13 airs Tuesdays at 9 p.m. (8 Central) on Syfy in the U.S.
