Pete and Myka investigate when a series of mysterious incidents occur at an expensive gated community, and soon discover that someone is using an artefact to get revenge. Meanwhile, Claudia and Artie must help a homeless boy experiencing recurring moments of mathematical brilliance, each of which is followed by a seizure of increasing intensity.

After bronzing Claudia, Paracelsus escapes with the only artefact that can reverse the process, and the team has to hunt him down before it's too late. Meanwhile, Claudia's link to Warehouse 13 endangers the building and Mrs. Frederic.

The Warehouse agents have to work against the clock to de-bronze a disintegrating Claudia and hunt down Paracelsus, Nick, and Sutton.
