“For a while I was feeling really lonely — that loneliness that you have even in a crowded room. But I don’t feel it anymore,” says Camille (newcomer Rachelle Vinberg) in a new trailer for Crystal Moselle’s “Skate Kitchen.” The teen’s loneliness is cured when she befriends a group of girl skateboarders.

Less impressed with Camille’s new community is her mom, who tries to make her promise that she’ll stop skating. Complicating matters even further is a mysterious skateboarder guy (Jaden Smith, “The Get Down”), who seems to drive a wedge between Camille and her friends.

“Skate Kitchen” marks Moselle’s first narrative feature. She broke out with the 2015 Sundance Grand Jury Prize-winning doc “The Wolfpack,” a portrait of six brothers confined to their home who learn about the world by watching films.

“I worked for over a year with a group of real teenage skateboarder girls to create a film that was semi based on their lives,” the writer-director told us. She met the characters from the story on the train and became friends with them.

Jen Silverman (“Ink”) and Aslihan Unaldi (“Young Wrestlers”) co-wrote the script.

“Skate Kitchen” made its world premiere at Sundance in January and hits theaters August 10.
