You were walking your dog, and... Did that ambulance turn into a robot? As soon as you thought things could not get any more crazy, blasts started firing at you. "Come with me. We don't have time." the Ambulance said, and soon enough, you were riding on an ambulance that was also an Autobot. The next day, that ambulance picks you up, and you, along with 3 pals at school, are there, as Optimus explained that all 4 of you were in danger due to the Decepticons and have to stay with them.
