"The Son of No One" follows two friends (Tatum and Morgan) forced to face the consequences of a murder they committed - and got away with - 16 years earlier. Tatum's character Jonathan "Milk" White has gone on to a successful career with the police force and has a happy home life with his wife (Holmes) and Child. Morgan's character Vinnie has kind of gone the other way. When Milk is assigned to the precinct where he grew up, his decade-and-a-half-old secret threatens to tear apart his life and his family.
