Betrayed and murdered by his underboss, a ruthless mafia don wakes up reincarnated as a two-year-old toddler. Trapped in diapers with the mind of a kingpin, he teams up with his preschool teacher to launch an undercover revenge scheme disguised as an innocent child. Using weaponized cuteness to bring down his betrayer, the pint-sized don fights to avenge his death, reclaim his soul, and find redemption in the healing warmth of a brand-new life.
