Gallan So Chi-Chiu

Once famous for his quick blade, a retired assassin can no longer earn a living with his cut-throat skills. Summoned again, he partners with his chauffeur to carry out special missions – fullfilling the wishes of old people looking to kill themselves. When commissioned by a young girl who has been deserted by her parents and lover, the "Elderly's Angel" squad finds an arresting way to complete its task.

When a terrorist who specializes in explosives takes hold of an underground tunnel, he threatens to kill hostages if his demands are not met.
