It's been years since the League Mafia was disbanded. Out on parole and stuck in therapy, Luke Walker is coasting through life. While he's no longer a villain, he's not exactly a productive member of society either. When an awkward past fling shows up, he's met with a surprise: a 3-month-old baby girl. Turns out motherhood is hard when you're a serial killer. Suddenly saddled with the responsibility of a child, Luke has a choice: keep his life the boring way it is or become a father for his kid he didn't know he had. He knows nothing about being a good parent, but help comes in the most surprising of forms, specifically Captain Lena Rose. All Lena wants to do is be a hero, so when she stumbles across the former villain with a baby, she can't help but worry. With Luke clueless, Lena decides to do her best to help. What starts out as a chance meeting between two old enemies turns into something else as they find themselves in a strange predicament and more people get involved. They say it takes a village to raise a child. Sometimes, it's a handful of mostly reformed mafia members and the Meta Detective Agency they tried to kill back in the days.
