A Killer Without a Grave (1961)

Nakata (Keiichiro Akagi) is a nihilistic young buck who is willing to do anything to get money in his pockets. As he knocks back a couple drinks that he knows he won't be able to afford, a former marksman-turned-bad, Ishioka approaches him. Ishioka is looking for an unaffiliated hit-man who is willing to handle some business. Nakata is just the right man for the job.
