In a Transformers spin-off, Bumblebee takes a look at our favorite transforming bot in his early years on Earth.

On the run in the year 1987, Bumblebee finds refuge in a junkyard in a small Californian beach town. Charlie (Hailee Steinfeld), on the cusp of turning 18 and trying to find her place in the world, discovers Bumblebee, battle-scarred and broken.
