Synopsis for the TV Cartoon Transport To Oblivion

The Decepticons, working out of an undersea base created from their crashed ship, create a "space bridge" back to Cybertron. Bumblebee and Spike are caught spying and are to be used to test the device which has already failed to work once. Bumblebee is reprogrammed to lead the Autobots into a trap, but Megatron must call off his assault on them since the space bridge is reactivated and must be used within a short period of time. Spike is saved by Bumblebee, and the Energon being transported is detonated, throwing Megatron into the bridge as it is activated.
