Gru & his wife & partner at work Lucy are assigned to apprehend  Balthazar Bratt, a former child star turned evil, from stealing the world’s largest diamond. Bratt dances his way to MJ’s Bad onto a navy ship and steals the diamond but Gru is able to stop him but the villain gets away. Gru and Lucy are fired from the AVL by its unreasonable new director Valerie Da Vinci, following the retirement of Silas Ramsbottom. As Gru mops around disappointed in letting down his kids, he is visited by  Fritz, the butler of Gru’s cheerful twin brother Dru, who lives in a distant country named Freedonia and longs to meet him. Gru is shocked to learn he has a twin. He confronts his mother, who reveals that when she and her husband divorced, they agreed to keep one child each.

Gru, Lucy and the girls are greeted with much job by Dru and are amazed by his apparent wealth. Meanwhile the Minions, led by Mel, who had left the house as Dru refuses to return to villainy, get arrested for trespassing at a talent show set. Bratt manages to steal the diamond again, intending to use it to power a giant robot and destroy Hollywood as revenge for the cancellation of his show. Gru then tells Dru the family secret – the pig farm is just a front and their father’s super villainy is the real reason for their massive wealth. Dru was dismissed by their father as he was no good at being a villain and was seen as a disgrace. The brothers bond as they drive their father’s gadget filled car.

Lucy tries to balance her tasks as a mom, which she exhibits after turning away a young boy named Niko who had fallen for Margo in the midst of a traditional cheese festival, while Edith and Agnes stumble into a local tavern and learn from the bartender about a mythical unicorn which lurks in a nearby forest. Gru tries to convince Agnes that unicorns are imaginary, but decides against it to avoid hurting her feelings. The next day, Agnes and Edith set out into the woods to track the mythical horse, only to find a one-horned goat whom Agnes adopts and dubs “Lucky.” Meanwhile, the Minions’ longing for Gru motivates them to escape from prison. Gru goes to steal the diamond back from Bratt and Dru tags along almost ruining things.

Gru secretly intending to bring it to the AVL, which he hopes will convince Da Vinci to rehire him. Despite several setbacks, they manage to retrieve the diamond and are rescued by Lucy after narrowly escaping. After finding out Gru’s true motives, Dru confronts his brother about his lie. In return, Gru insults him and decides to leave Freedonia. Bratt, disguised as Lucy, kidnaps the children, and once again acquires the diamond. Gru and Dru resolve their differences and pursue him. Powering his large robot with the diamond, and superpowered gum, Bratt terrorizes Hollywood Lucy saves the children while Gru and Dru weaken Bratt’s robot with the weapons of their father’s car. Gru is knocked unconscious when the car is destroyed, and Dru manages to destroy the robot’s core from the inside when Bratt threatens to kill Gru.

When Gru recovers, he battles Bratt in a dance fight, using it as a distraction to grab his weaponized keytar, and defeats him. Having rendezvoused with Gru, the Minions manage to destroy the gum already covering the city, and Gru and Dru reunite. Soon afterward, Gru and Lucy are reinstated in the AVL and the newly united family celebrate in Gru’s home. Lucy is acknowledged by the children as their mother. Lured back to villainy, Dru and most of the minions steals Gru’s ship, with Gru’s emblem replaced with a “D” graffiti. Gru and Lucy decide to give them a five-minute head-start before engaging pursuit.

Funny and sweet, just like the others though I want more Minions, it is a good movie to watch even at midnight. I love it. 8.5 outta 10!
