The criminal Boris the Animal (Jemaine Clement) escapes from the LunaMax, a moon-based maximum security prison. He comes to Earth seeking revenge from Agent K (Tommy Lee Jones) that has blown his arm up 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.
When Agent J (Will Smith) notes that the time line has changed in the present days and Agent O (Emma Thompson) tells him that K died in 1969, he decides to travel to 15 July 1969 to save K on the next day. Agent J has difficulties to convince the Young Agent K (Josh Brolin) 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 (Michael Stuhlbarg) that has precognitive powers and gives the ArcNet to K to protect Earth from the Boglodyte invasion. Further, J learns a secret about K and himself.
"Men in Black 3" is a great adventure of this franchise, with a wonderful story and magnificent special effects. I had low expectations with movie, but I was favorably surprised with an adorable film. My vote is seven.
Title (Brazil): "MIB³ - Homens de Preto 3" ("MIB³ - Men in Black 3")
