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 most unusual Boss Baby (Alec Baldwin) arrives at Tim s home in a taxi, wearing a suit and carrying a briefcase. The instant sibling rivalry must soon be put aside when Tim discovers that Boss Baby is actually a spy on a secret mission, and only he can help thwart a dastardly plot that involves an epic battle between puppies and babies.. The story line is quite an imagination. The babies these days are truly Bossy. Celebrate the birthday of your Boss Baby with the decor personalized with his photo and details. Heritage Kit is Available for Boss Baby Theme.
