Based on the autobiographical graphic novel of the same name by Phoebe Gloeckner, Diary of a Teenage Girl was one of the breakout hits of Sundance this year, and will now be hitting theaters this summer thanks to Sony Pictures Classics, which snapped it up during this year's festival. Set in 1970s-era San Francisco, SFist first caught wind of the production back in early 2014 when stars Alexander Skarsgard and Kristin Wiig were spotted at location shoots around town.

As you can see in the lush, Instagram-filtered trailer brought to us today by Yahoo Movies, it's a coming-of-age tale centered on 15-year-old Minnie Goetze (played by 23-year-old British actress Bel Powley) as she comes into her own, sexually. She's encouraged by a libertine mom (played by Wiig), and then has an affair with the handsome, older Skarsgard, who is actually her mom's boyfriend.

The film provides a judgement-free look at young Minnie's budding sexuality, and as the NYT's Manohla Dargis wrote that director Marielle Heller "pulls off the tricky feat of honoring Minnie's sexuality without exploiting it or her."

Diary of a Teenage Girl opens in select theaters on August 7.
