In Her Final Coup, aging gang leader Gianna devises a plan to rob a bank and safely transport the money to her. Four messengers are assigned, two each, to bring the loot to her. On their way, however, the Vulture gets in their way, a masked criminal who ambushes bank robbers and dealers, kills them, and disappears with their loot. While Gianna waits with her subordinate Elijah for the money to be handed over, the young couriers become part of a nightmarish chase. But the gang leader is also confronted that evening with events that lead her into the abysses of the human psyche.
