From the day the boss baby arrived in a taxi, life would never be the same for his older brother Tim. Sure, the boss baby had Tim's parents wrapped around his chubby little finger, but Tim knew the truth: This was no ordinary baby. He held meetings. He could talk. And he was on a mission to stop Puppy Co. from putting Baby Corp out of business. But the boss baby needs Tim's help. And if the boss baby doesn't succeed, he'll be fired from Baby Corp, and these two rival siblings will be forced to be brothers forever. Can Tim make a deal with the boss baby, stop Puppy Co., and get the boss baby out of his life for good? And will the boss baby finally get the corner office with the private potty he deserves?
