Keira Knightley experiences some arrested development and is egged on by Chloe Moretz, an actual teenager, in the first trailer for Lynn Shelton‘s Sundance hit, “Laggies”, TheWrap reported.

Knightley's Megan, yet another twenty-something adult having trouble adjusting to having responsibilities and growing up, runs for cover — literally — when her boyfriend (Mark Webber) proposes. She hides out at the home of Moretz's character Annika, and this dysfunction junction gets even more complicated when Annika's dad (Sam Rockwell) discovers the situation.

“Laggies” premiered at the 2014 Sundance Film Festival, where it was picked up for distribution by A24. It will be released on October 24.
