A story about how a new baby's arrival impacts a family, told from the point of view of a delightfully unreliable narrator, a wildly imaginative 7 year old named Tim.

The Templeton brothers — Tim and his Boss Baby little bro Ted — have become adults and drifted away from each other. But a new boss baby with a cutting-edge approach and a can-do attitude is about to bring them together again … and inspire a new family business.
