Starbuck focuses on David Wozniak, a lovable, middle-aged man who's a bit of a train-wreck. A disappointment to his family and his pregnant girlfriend Valerie - he also owes a decent amount of money to some loan sharks. Yet things are about to get even worse. His life is upended when a lawyer informs him he's fathered no less than 533 children via his regular sperm bank donations more than two decades earlier, under the nickname Starbuck. And now a hundred or so of the young-adult offspring have gotten together to take legal action to reveal the true identity of their father.
