Set in a retro-tinged modern city, The Don’s Soft Vow follows Sofia, the sharp, unassuming daughter of the Acton mafia family, recognizable by her signature dark brown braided pigtails, tiny pearl studs, and go-to cream double-breasted trench coat layered over a lace-collar blue button-down shirt, whose carefully restrained, quiet life shatters the second she learns her father has been murdered. Her only unshakable confidante, a close friend in a light brown short coat and pink trousers, tries to steady her as Sofia breaks down screaming in the warm vintage parlor, where an hour prior her friend had hidden an unknown black item beside the room’s well-loved old wooden piano.
