Over three episodes, three respectable middle-aged men find themselves behaving badly. A teacher hides his pornographic magazine from a female student. A jogger steals milk and blames it on a newspaper delivery boy. A drunk man desperately searches for a public toilet late at night.

A notorious dirty cop makes an honest attempt to catch a serial killer who even murdered his own parents.

Four unlikely assassins question their assignments because they genuinely care about their customers and victims. However, they attract police attention and a prosecutor is on their trail.
