This is where it all begins...the very first shots fired in the civil war between the heroic Autobots, led by the noble Optimus Prime, and the evil Decepticons, ruled by the crazed Megatron! A spaceship launched from the planet Cybertron crashlands on Earth, four million years in the past. In 1984, its inhabitants are awakened - and Earth is plunged into the middle of the greatest conflict it has ever known, with teenager Buster Witwicky and his mechanic father caught in the middle, as Autobots and Deceptions alike battle for fuel and technology! Now it is up to Optimus Prime and his few remaining allies to protect both themselves and their human friends from the threat of Megatron...but surprises galore lie in store for both robotic leaders!
