In the heart of the 1970s, Gru is growing up in the suburbs. A fanboy of a supervillain supergroup known as the Vicious 6, Gru hatches a plan to become evil enough to join them. Luckily, he gets some mayhem-making backup from his loyal followers, the Minions. Together, Kevin, Stuart, Bob, and Otto - a new Minion sporting braces and a desperate need to please - deploy their skills as they and Gru build their first lair, experiment with their first weapons and pull off their first missions.
