"In Broad Daylight" tells the story of the fanatically-uncompromising Len Rowan and his family, who insult and terrorize the citizens of a small town for years.
One day, a saleswoman's comment about Len's son not paying for candy triggers his persecution complex. In revenge for the believed insult, the whole family starts stalking the shop owner and her husband, leading to the old man getting badly injured.
Len is arrested but is freed on bail. His clever attorney delays the court session for more than a year, during which Rowan continues to threaten the witnesses.
The people in the town feel they've had enough of this and decide to take the law into their own hands.
