Pete tries to adjust to a new partner while investigating a string of bizarre deaths in Denver. The last words of the victims leads the agents to an old friend. Meanwhile, Artie and Claudia try to stop a lightning storm in the Warehouse.
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.
