Hachiro is a former boxer, now working as a debt collector for a finance company. He is sent to collect money from Kazuma, a former trainee doctor who has fallen on hard times ever since the suicide of his girlfriend. Hachiro pursues Kazuma into a bank, where Kazuma convinces the staff that the debt collector is, in fact, an armed robber. Although he is falsely arrested, Hachiro develops a liking for the roguish renegade and even offers to help him evade other debt collectors.
