The story revolves around Tim Templeton, a seven-year-old boy who has a vivid imagination. His perfect life is disrupted when his parents bring home a new baby who wears a suit and carries a briefcase. The baby, known as the Boss Baby, is on a secret mission for Baby Corp, an organization in charge of managing the balance of love between babies and puppies.

In the climax, Tim and the Boss Baby infiltrate Puppy Co.’s headquarters to stop the launch of the new puppy. They discover that the head of Puppy Co., Francis Francis (voiced by Steve Buscemi), was once a Baby Corp. employee who was fired and holds a grudge against babies.
During the confrontation, Francis unveils a secret weapon – a formula that can turn babies into adults and make them forget they were ever babies. The Boss Baby, being exposed to the formula, begins to age rapidly. Tim, realizing the importance of his brother, decides to sacrifice his memories of being the only child to save the Boss Baby.
