BabyCo is the world's leading manufacturer in baby products. However, what the public doesn't know, is that Drs Kinder and Heep, two of its most brilliant scientists, are tirelessly working in complete secrecy to crack the indecipherable code to 'baby talk': a highly sophisticated language, and the key to the secrets of the universe. Before long, problems arise when mischievous Sly, the smartest of the toddlers, escapes confinement, bent on uniting all babies to free those trapped in the laboratory. Now, Kinder and Heep must find Sly before it is too late.

Babies can communicate with each other using 'baby talk', and have innate knowledge of the secrets of the universe. The infant geniuses become involved in a scheme by media mogul Bill Biscane. Assisting the geniuses is a legendary superbaby named Kahuna, who joins up with several other babies in an attempt to stop Biscane, who intends to use a state-of-the-art satellite system to control the world's population.
