Louis, a young einstein living in an orphanage, dreams of having a family. Wilbur, a boy about the same age, desperately seeks the help of the boy genius. After some convincing, the two boys go to Wilbur's house. Louis meets Wilbur's mom, a zoologist. Being a science wiz, that's something Louis appreciates. Louis meets some of Wilbur's other family members: a fashion designer, an artist, and others who succeed in their respective fields. More than that, they don't take themselves too seriously.

The zaniness continues with a food fight over dinner. Louis is having the time of his life. But he is really over the moon when, after finding out that he's an orphan, Wilbur's family offers to adopt him. Not only has Louis dreamed about being adopted, but to the child prodigy, a family of scientists and creative people would be the best family on the globe.

His ecstasy takes a sharp nosedive when this family realizes who he is. This family is besides themselves with shock. Very apologetically Wilbur's mom tells Louis how sorry she is but he has to go back to where he came from.

Crushed and confused, Louis asks what's the big deal. He has no idea what's going on. One minute this family was about to adopt him and the next they tell him that he needs to go back to the orphanage. Devastated, Louis, of course, runs off.

In the end, Louis learns who he is and what happened the night that his mom dropped him at the doorstep of the orphanage.
