For years, Earth is repeatedly attacked by giant monsters called Kaiju that emerge from a portal beneath the Pacific Ocean. The only effective defense is the Jaeger program, massive complex robots that require pairs of neural-linked pilots. However, as each Kaiju attack becomes more powerful and frequent, Humanity must change its tactics. To that end, former Jaeger pilot Raleigh Becket is reactivated as part of a desperate plan to destroy the portal. As Raleigh strives to heal his inner scars and help his new partner conquer hers, an intrepid scientist discovers a way to link to the Kaiju’s mind to learn about them. Unfortunately, that proves a mixed blessing as vital information of both sides is inadvertently shared and the stakes rise for a final battle.
