Even serial killers face their own existential crises: Arthur, after many years of happy activity, begins to wonder if it is not appropriate to stop killing, but it is not so easy.
Helping an old lady with the grocery shopping could be a good start for Arthur towards "redemption". However, it is still difficult for him to resist temptation.
Arthur is looking for a hobby to extricate himself from own murders. He then makes an attempt at fishing, but an unfortunate fisherman and his petulant wife pay the price.
Who is Cordelia? Unscrupulous policewoman, but also a single woman who does not remain insensitive to Arthur's charm. Between the two, however, things inevitably get complicated.
Arthur's life now seems quiet, but in reality it is not: the policewoman is investigating the murder of a fisherman. In addition, Zed, a friend that Arthur goes to visit in the elderly home, hides many surprises.
Between Arthur and Cordelia it seems that things are getting better and better; but how long will it be before the policewoman discovers that the killer she's looking for is the very humor that brings her out to dinner?
