Uri loans Lenny a "lucky painting" as a symbol of trust, instructing Lenny to hang it in his office. However, the painting is soon stolen from Lenny’s safe by his own slippery stepson, a drug-addicted rocker named One-Two, alongside his loyal partners Mumbles and Archy, Lenny’s sophisticated second-in-command.Simultaneously, Uri’s cunning accountant, Stella, orchestrates a plot to embezzle the seven million euros from her boss. She hires One-Two’s crew to intercept the cash delivery intended for Lenny. Desperate to launder the stolen millions, the gang approaches two crooked accountants who happen to be managing the finances of Johnny Quid, the presumed-dead rock star who is actually One-Two’s idol and Lenny’s resentful former stepson.As the net tightens, Uri grows furious over the missing painting and pressures Lenny to recover it.
