In this third entry in the long-gestating franchise, Mike Lowery (Will Smith) gets gunned down by up-and-coming Miami crime kingpin Armando Armas (Jacob Scipio) who pops a few rounds into the cop at the direction of his ruthless mother Isabel (Kate del Castillo), getting revenge on all of those cops and lawyers who took down her drug-lord husband years before. Due to Marcus Burnett (Martin Lawrence) making a pact with God to hang up the “bad boys” life if Mike pulls through, he refuses to join forces with his longtime partner on exacting revenge on Armando. To help supplement the cover, loose-cannon Mike teams up with the by-the-book ‘AMMO’ division of the force, a group of young guns with high-tech weapons. Of course, when tragedy strikes once again, Marcus gets off of his recliner for one more chance at the guts and glory of the “bad boys.”
For this fourth entry in the series, out are Will Smith and Tommy Lee Jones. Instead, we get two new characters to follow working for the super-secret government organization to protect Earth from interdimensional threats and to keep knowledge of alien lifeforms away from human knowledge. The two are Tessa Thompson’s newly on-board Agent M and Chris Hemsworth’s roguish veteran named Agent H. The two “Men in Black” get their assignment from their boss, High T (Liam Neeson), to look after an alien of some renown and influence that is sought after by sinister forces for reasons come to learn more about through the course of the film. In the ensuing attempt at assassination, M is given a mysterious crystal object, one she knows must be important enough to make her a target, but something that serves no use to her until she can unlock its secret purpose. F. Gary Gray takes over the series from Barry Sonnefeld.
