Arcee, Bulkhead, Jack and Miko are out investigating a seemingly abandoned mining cave. However Megatron picked this very day and cave to execute the traitorous Starscream, and when the two factions clash, it results in a massive cave-in, trapping them under the rocks.

Miko accidentally downloads ancient knowledge stored on a data cylinder into Bulkhead's brain. The Autobot gains tremendous amounts of information, but it's threatening to delete his own personality if the data is not removed from his system.
