Minions & Monsters introduces us to an entirely new tribe of Minions, who find themselves in Hollywood at the dawn of cinema. Our heroes are two brand-new Minions: James and Henry. We meet them and their rambunctious friends in the distant past and witness their trials and tribulations as they search far and wide for an evil master to serve. Eventually they reach the 1920's, and wind up crashing a Hollywood film set. Their brief and accidental appearance on camera pays off and before they know it the Minions are bona-fide movie stars. They begin to live the Hollywood lifestyle, and soon they're throwing lavish parties, living in a huge mansion, and inspiring an army of fans to dress in overalls and goggles.
The Minions' 15 minutes of fame are soon up, however. With the addition of sound to film and the rise of the "talkies," they drop in popularity – it turns out they can't follow the script when all they speak is Minionese. Destitute and aimless, the Minions roam the streets of Hollywood looking for a purpose…and a new evil master to serve.
Our heroes James and Henry have a different plan and break away from their tribe. They have fallen in love with making movies and want to make an awesome monster movie of their own! With the help of a spellbook taken from an old boss (an evil sorcerer they used to work for), James and Henry summon some fearsome monsters to play the villains in their movie. When things go haywire, James, Henry, and all their buddies must work together to save the world from a band of rampaging monsters.
