The featured film in the next Movies That Matter program is “Idle Threat.”

The film is described as a lively look at one man’s spirited struggle to improve public health by raising awareness about the impact of idling cars on public health.

An expert on air quality and an expert on public health will converse after the film.

The movie will be screened at 7 p.m. Thursday, April 4, at the Bainbridge Public Library.
