This movie might be a good one, I’ve just seen the trailer and liked it. The trailer gives you the reason of the plot. They have the guts to mention the police vs black people problem and dare to curse on film.
THREE BILLBOARDS OUTSIDE EBBING, MISSOURI is a darkly comic drama from Academy Award winner Martin McDonagh (IN BRUGES). After months have passed without a culprit in her daughter’s murder case, Mildred Hayes (Academy Award winner Frances McDormand) makes a bold move, painting three signs leading into her town with a controversial message directed at William Willoughby (Academy Award nominee Woody Harrelson), the town’s revered chief of police. When his second-in-command Officer Dixon (Sam Rockwell), an immature mother’s boy with a penchant for violence, gets involved, the battle between Mildred and Ebbing’s law enforcement is only exacerbated.
