An absent-minded bachelor spends his life inventing things and going to school, but he never finds time to learn everything he wants to know. He is interested also in his young nephew and the nephew's wife, and he drops in on the couple on his way south. Having money, he wants to make the young people comfortable but is especially concerned in giving them an incentive to raise a family, and he is anxious to provide bonuses for children who will come later on. When he arrives he mistakenly identifies a charming bride, a neighbor of the young people, as his nephew's wife. For sufficient reasons, the truth is concealed. In order not to disappoint Uncle, all the young people involved must play out the comedy until almost the very end. What with this bride and that dashing in and out, and Uncle meantime happily involved in his schemes for helping his own young people, we are involved in a series of misadventures. But Uncle finally gets everything straightened out and generously gives presents not only to his nephew and his wife but to everyone else.
