Santino D’Antonio, a powerful Italian crime lord, arrives at John’s doorstep. He carries a "Marker"—a blood oath John swore years ago to secure his retirement. Santino wants John to assassinate his own sister, Gianna, so he can take her seat at the High Table, the supreme council of global killers.
