The Nice Guys (15)

Jackson Healy is a hired heavy in 1977 Los Angeles, who beats up perverts and stalkers with his knuckleduster. A young woman called Amelia Kuttner pays him to scare off low-rent private detective Holland March, who has been asking for her around town. The first meeting of these two men ends in bloodshed and broken bones, but Jackson and Holland reluctantly agree to work together when Amelia subsequently vanishes without trace.
