Master thief Stan Kovacs assembles a team of professional thieves, who the police believe intend to steal the Mask of Rasputin from the museum of natural history. While they are distracted guarding it, Kovacs masterminds a string of robberies across Central City, which are foiled by the Flash, and in the process Barry learns that Kovacs is using the other criminals as a diversion so his accomplice Celia Wayne can steal the relic from the museum's curator and Barry's mentor, Ted Preminger. The Flash catches up to Kovacs and Celia before they escape with the artifact and brings them to justice, insuring that Preminger can finance the museum with the Rasputin Mask exhibit.
