Summer vacation. 1979. Brothers Trevor & Junior Atwood share everything - friends, stories at night, a bunk bed - but as older brother Trevor prepares for high school, the two must confront how their brotherhood will adapt against the current of changing times. Taking place entirely in their shared bedroom, 'Night Light' offers a glimpse behind closed doors to a time when you could ask who else is still awake, and to a place where big brothers reign supreme.
