Set right after the events of the first film, this time in the 1970s, a 12-year-old Gru grows up in the suburbs. A fanboy of a group of supervillains known as the Vicious 6, Gru hatches a plan to become evil enough to join them. When the Vicious 6 fire their leader, the legendary fighter Wild Knuckles, Gru is interviewed to become their newest member.
It doesn’t go too well, and things only get worse after Gru steals a precious stone from them with the help of Kevin, Stuart, Bob, Otto and the other Minions and suddenly becomes the mortal enemy of the pinnacle of evil. On the run, Gru and the Minions will turn to an unlikely source of guidance, Wild Knuckles himself, and discover that even bad guys need a little help from their friends.
