From the liner notes

Three million years after crash-landing on an unfamiliar planet, sentient robots with the ability to disguise themselves as common vehicles awaken on present-day Earth. Engaged in a crucial race to find a new energy source for their home planet of Cybertron, the heroic Autobots must defend the innocent people of Earth against their arch nemeses, the power-hungry Decepticons.

For 25 years the war between the peace-loving Autobots and the villainous Decepticons has captivated children and adults alike, launching countless collectible toys, comic books, animated series and feature films beloved by loyal fans. Now you can return to where the phenomenon began with the original "Transformers: The Complete First Season."
