A boy determined to save his father's failing private detective business enlists the help of his pet dog and parrot...who talk. Together they will try to take down the town's tyrannical tycoon who's determined to stop a mansion from being turned into an animal rescue.

After seven months have passed without a culprit in her daughter's murder case, Mildred Hayes makes a bold move, painting three signs leading into her town with a controversial message directed at Bill Willoughby, the town's revered chief of police. When his second-in-command Officer Jason Dixon, an immature mother's boy with a penchant for violence, gets involved, the battle between Mildred and Ebbing's law enforcement is only exacerbated.
