Anonymous Content has set Humpday writer-director Lynn Shelton to direct the Andrea Seigel-scripted indie Laggies.

The film follows a woman who, unsure of how to respond to her boyfriend's marriage proposal, pretends to go on a retreat but actually ends up spending a week with her new friends, all of whom are in high school.

The main character is described as a 28-year-old who has been living in perpetual adolescence, as she never switched over to the formality that adulthood imposes.

No reports on the timeline for Laggies have been released.
