Criminal Boris the Animal (Jemaine Clement) escapes from LunarMax, a moon-based maximum security prison. He comes to Earth seeking revenge on Agent K (Tommy Lee Jones), who shot off his arm and arrested him forty years ago, and protected Earth from a Boglodyte invasion. Boris is defeated again, and he travels back in time to 1969 to kill Agent K (Josh Brolin). When Agent J notes that the timeline has changed in the present day and Agent O (Dame Emma Thompson) tells him that K died in 1969, he decides to travel to July 15, 1969 to save K the following day. Agent J has difficulties to convince the Young Agent K with lies, but when he decides to tell the truth, K believes in his words and they seek out Boris together. They are helped by the amicable alien Griiffin (Jemaine Clement), who has precognitive powers and gives the ArcNet to K to protect Earth from the Boglodyte invasion. Furthermore, J learns a secret about K and himself.—Claudio Carvalho, Rio de Janeiro, Brazil
