The Autobots discover that an Energon Harvester, an ancient and powerful device from Cybertron's distant past, is on display in a museum, and they attempt to retrieve it with Jack, Miko and Rafael's aid before it falls into the wrong hands. Starscream also learns of the Harvester's whereabouts, and he sends Soundwave, along with new Decepticons Knock Out and Breakdown, to obtain it.
