Dziki Bill Sezon 1 Odcinek 6

On his way home from work, Bill finds five charred bodies atop a bonfire on the roadside, close to a local farm. Pathology reveals that all five victims had been shot through the head with a nail, although this was not the cause of death. Raking through cases with a similar MO, Bill uncovers a series of murders committed by Frank McGill, a former hitman who has been in witness protection since 1997, having given evidence to the justice system that implicated his former gang's boss.
