Transformers Prime Season 1 Episode 15

Starscream begins plotting his revenge against the newly revived Megatron by stealing a Dark Energon crystal with which he plans to resurrect Skyquake. But when Miko and the others follow the Autobots to Starscream's coordinates, the two competing GroundBridges malfunction and accidentally send the kids to an alternate astral plane where they can't be seen or heard by the Autobots. Unfortunately, Skyquake is also stuck in the Shadowzone with Miko, Raf and Jack, putting their lives in danger.
