It (2017 film)
Around June of 1989, Mike is assigned to kill a sheep with a bolt gun, which he is reluctant to do, much to the annoyance of his grandpa, Leroy, who does it for him and then berates his grandson for not taking responsibility.
Later that day, Mike bikes into town to deliver some meat to the Quality Meats store. He puts his bike against a streetlight in front of the store so he can carry the meat to the "Deliveries Only" door in the adjacent alley, but then goes into the alley to hide from Henry Bowers and his thugs, who are driving down the street. Coming to the delivery door, he hears voices and sees charred hands coming out from the door; the door then opens, and he sees the shadowy shape of Pennywise through a wall. Henry and his pals suddenly speed towards him, nearly running him over; Henry threatens him and throws a cigarette at him while Belch gives him the "finger". After they leave, the store manager comes out to see what the commotion was all about, finding Mike on the ground and asking if he's okay.
A few days later, Henry, Vic, and Belch, minus Patrick, who was killed by Pennywise, are torturing Mike by the river. Luckily, Bill, Beverly, Ben, Eddie, Richie, and Stan turn up to rescue him and fight against Henry and his goons. A grateful Mike joins their group, known henceforth as "The Losers Club", while telling them that picking a fight with Henry was a bad idea, because he'll be after them as well. Eddie tells Mike that they're all major targets for Henry.
During the Fourth of July, Mike and the others talk about how kids vanishing seems to be all too common lately. Ben tells them that he's gone over his history of the town and discovered that all the events from the past have one thing in common: they only occur every twenty-seven years. Mike adds that his grandpa has always believed the town is haunted. They each discuss some of the frightening things they have seen in recent days, and acknowledge that everyone has something that they fear more than anything else.
At Bill's house, they use a map and projector to pinpoint the locations of the past incidents, and learn that each of them are connected by the sewers, which converge at the Well House. After Eddie tears down the map, they are attacked by a gigantic Pennywise. Bill decides it's time to take action and goes to the Well House alone. The others try to stop him, without success. While Eddie and Richie follow Bill inside, Ben, Beverly, Mike, and Stan wait outside. However, they are easier prey for Pennywise, because there's only three of them. Luckily, the others step in to rescue them, though Ben and Eddie are both injured in the encounter.
Escaping from the house, they bring Eddie home, where his mother reprimands them for his injury and refuses to hear them out. As Richie, Stan, and Ben, angry with Bill for almost getting them killed, leave, Mike also drops out of the group, confessing that he's an outsider, just like his grandpa said, and that's the way it has to be, despite Beverly's attempt to convince him to stay with them.
However, Mike rejoins the group after Pennywise takes Beverly prisoner in August. Returning to the Well House, Bill leads them down to the basement where he saw the well during their previous incursion. As Mike is about to follow the others down the well, he is ambushed by Henry, who has become a deranged psychopath because of It and tries to kill him, but Mike retaliates by hitting him with a rock and then pushing him into the well, seemingly killing him. As he tries to load his gun, his ammo accidentally falls down the well.
After losing track of Stan, and then Bill, Mike and the others get to Pennywise's Lair, where they find Beverly, entranced and levitating after being exposed to It's true form. Mike and Richie help Ben to get Beverly down, and they, along with Eddie and Stan, express amazement when he brings her back with a kiss, then embrace the two of them as they express their feelings for each other.
