From the introduction:

While chasing criminal descendants of the Decepticons known as Predacons led by the renegade Predacon Megatron the crew of a Maximal (Descendants of the Autobots) ship led by Optimus Primal find themselves thrown through a rift in space known as a transwarp portal, during a quick but harsh firefight both ships are badly damaged and fall from orbit while losing their precious cargo of unactivated maximal protoforms in space due to the damage done to their ship.
