The alternate-timeline Valda makes his move, using Claire as his mindless slave. As Valda sets out to move Warehouse 13 to a new location that he can control, the team races desperately to stop him before it's too late.
After bungling a government case, a federal forensic accountant and an assistant U.S. attorney are banished to Warehouse 13, a storage facility in nowhere North Dakota, where they must spend their days cataloguing thousands of artifacts, relics and other odd detritus collected by our government over the centuries.
They quickly discover that each strange item has a story... and often the stories involve the supernatural, the extra-terrestrial, the fantastic and/or the downright bizarre.
