Described as a dramatic musical with a fresh spin, the pic is an energetic, affecting anthem of contemporary teenage life. The movie follows two young couples as they navigate the emotional minefield of growing up and falling in love.

“Waves” will be produced by Kevin Turen and Jim Wilson.
The pic marks the third collaboration for Shults and A24, who previously worked together on “It Comes at Night” and “Krisha.”
