Cellphone recording of two boys asking Superman what's his favorite thing about Earth. He just smiles.
Crits Montage about violence and crime escalating since Superman's death.
Gotham. Batman is investigating Parademon sightings and has figured out that they are drawn to fear. He hangs a thug off a roof so his fear attracts a Parademon and plants a tracker.
Victor Stone hides out in his apartment. He was a college football star who got mangled in a car crash. His father Silas Stone used an alien Mother Box to revive Victor, turning him into a cyborg. He's concerned because he's developed new powers - he can fly now, and he doesn't know where the power is coming from.
Central City. Barry Allen meets his father Henry in prison. Barry got superspeed after being struck by lightning. Henry was framed for his wife's murder. Barry is studying forensics and wants to get a job in criminal justice to get him out, but his dad wants him to give up that pursuit and just live his life. Funny gag of Barry drawing a mustache on an asshole guard without him noticing.
London. Wonder Woman stops terrorists in the courthouse. Their leader is Roose Bolton from "Game of Thrones" and unloads an automatic rifle on a group of schoolchildren, but Diana deflects every bullet.
Themyscira. Steppenwolf comes through a portal to steal a Mother Box. The Amazons try to play keep away with the box, tying it to arrows and firing it off before Steppenwolf can get it. But he eventually does and taunts Diana's mother Hypolita before disappearing with the box.
Hypolita orders that they fire a giant arrow to signal Diana that an invasion is coming. Diana sees a television report about it and knows what it means.
Bruce talks to Alfred in the Batcave - Alfred eggs him on about liking Diana.
Diana visits Bruce at the Batcave. Funny gag as she easily goes through Bruce's super security system. They discuss Lex Luthor's journal - it has pictures of Parademons and Mother Boxes.
