Rating: TVY7. For many years, Earth has been free from the dangerous Decepticons. However, all of that changes when a maximum security prison ship containing about 200 Decepticon prisoners crashes on Earth and the prisoners escape. Optimus Prime orders Bumblebee to protect Earth from these dangerous Decepticons. This task is even more challenging as Bumblebee has to adjust to his new role as leader and learn to work with the diverse Autobots on his team.
