The first movie's framing device is Tim — the older brother — telling the story to his daughter, Tabitha; it ends with the reveal that her younger sister Tina is also a Boss Baby. Based on the trailer, we know "The Boss Baby: Family Business" will be set soon after Tina arrives, when the brothers of the original film are all grown up.
Now, Boss Baby — aka Ted — is a successful adult, but there's a rift between him and Tim. Their relationship will be put to the test when Tim's young Boss Baby daughter enlists their help to foil the plan of a man training babies to be terrible. The only catch? They have to de-age themselves to their ages from the first movie in order to stop Dr. Armstrong, but there's a 48-hour time limit and also baby ninjas in their way.
It should be a great deal more ridiculous and absurd than the first, and a delight for kids this summer.
