When a blizzard threatens to ruin Valentine's Day, three seventh-grade friends make and distribute fortune cookies to their lonely neighbors—and confront the secrets they've been keeping from one another.

Confident Kate doesn't notice much but the latest gossip, and shy Georgia can't say out loud what's always on her mind. They're joined by observant, careful Olivia, whose epic, single-minded crush on PBJ (real name: Phillip Becker-Jacobs) is starting to frustrate them. Using fortune cookies that mysteriously always seem to speak directly to the person who opens them, the three girls try to work together to bring some love to their building while reminding each other why they're such good friends to begin with.
