This film is the third installment in the Despicable Me series. This time the film tells the story of former villain Gru who is now an agent for the Anti-Villain League. He and his wife Lucy Wilde are sent to thwart the plans of Balthazar Bratt, a former child actor from the 1980s who turned evil after his TV show, “Evil Bratt” was canceled.
Gru manages to stop Bratt from stealing the Dumont Diamond, a giant pink diamond, but is unable to capture it. As a result of failing to catch Bratt, Gru and Lucy are expelled from the anti-criminal league they now lead, Valerie Da Vinci, following the retirement of former director, Silas Ramsbottom.
Later, in Despicable Me 3, Gru and Lucy return home. The two reluctantly tell their children, Margo, Edith, and Agnes, about their dismissal. Gru and Lucy convince the three that they will find a new job. Unfortunately, Gru, who is always accompanied by his Minions, must be willing to be abandoned by most of them when Gru refuses to return to being a villain. Only two Minions named Dave and Jerry.
The next morning, when a butler named Fritz arrives at Gru’s house. Gru finds out that he has a twin brother named Dru, who lives in a faraway country called Freedonia. Dru wants to meet him. Surprised to learn this, Gru goes to his mother. Apparently not long after they were born, she and her husband divorced. They each took one son to raise on their own and promised never to see each other again.
Gru and Lucy decide to meet Dru. They were surprised by his lavish wealth and the large size of his house. At the same time, Minions are arrested for trespassing at a talent show, shortly after they finish performing. Bratt himself manages to steal another diamond, intending to use it to power a giant robot and destroy Hollywood in revenge for his show being cancelled. Gru then decides to help the minions and defeats Bratt again.
