Long before he becomes the master of evil, Gru is just a 12-year-old boy in 1970s suburbia, plotting to take over the world from his basement.

In the 1970s, young Gru tries to join a group of supervillains called the Vicious 6 after they oust their leader -- the legendary fighter Wild Knuckles. When the interview turns disastrous, Gru and his Minions go on the run with the Vicious 6 hot on their tails.

Luckily, he finds an unlikely source for guidance -- Wild Knuckles himself -- and soon discovers that even bad guys need a little help from their friends.
