The battle for Earth is no longer just a fight for survival—it’s the final stand against a cosmic force that could end everything.

Sam Witwicky (Shia LaBeouf) thought the war between the Autobots and Decepticons was over. But when the ancient and destructive force of Unicron awakens, a force of unimaginable power, the Earth faces its most devastating threat yet. As Optimus Prime (Peter Cullen) and the Autobots prepare for the ultimate battle, Sam finds himself once again caught in the crossfire of a war that spans the universe. This time, however, the stakes are higher—this isn’t just a battle for the planet, it’s a battle for the very soul of humanity.

With time running out, Sam must team up with new allies, including the fierce and determined Alina (Rosa Salazar), whose past holds a secret that could shift the tides of war. But as Unicron’s power grows, the world around them shatters—familiar cities fall, and hope begins to fade. “In the end, it is not the machines that define us, but the will of those who choose to fight for what is right.”
