Sundance Film Festival darling The Diary of a Teenage Girl (finally!) has a trailer. The coming-of-age film based off Phoebe Gloeckner’s 2002 graphic novel adapted for the screen by Marielle Heller, recounts the adventures of San Francisco teen Minnie Goetze in the 1970s.

The film follows Goetze (Bel Powley) as a girl who loses her virginity to her young mother’s boyfriend (Alexander Skarsgård) making her officially “an adult.” Soon, she is consumed by thoughts of sex and men as she delves further into a sexual evolution.

According to Powley, it was her first time kissing on camera—and stripping down. “Because I was trying to portray something real, and I wasn’t trying to be beautiful or sexy, there was less pressure on me,” the actress told EW. “It was a relief, and I hope it starts a trend. It’s annoying when you’re watching a movie and you can see that the woman has tons of makeup on, it’s shot from [a flattering] angle, and there’s lighting to make her look skinny. It’s annoying as a viewer and it’s annoying as an actress.”

The Diary of a Teenage Girl premieres in theaters on Aug. 7.
