11-year-old sister, Lily, puts airport security to shame with how closely she monitors her 13-year-old brother, Mark. His every misstep goes into the little sister’s mental notebook. The bed isn’t made, the shoes are in the hallway, she calls in the mom, Sarah, faster than you can say family meeting. The younger sister ups the ante by broadcasting Mark’s secret crush to anyone within shouting distance, turning privacy into folklore and childhood secrets into gossip.

Mother, Sarah, runs the home like a luxury day spa for tattling. Each complaint is met with approval, each fake-cry gets an instant response. The dad is pulled into the mess as the only adult in the room who thinks the older brother, Mark, deserves a door that closes and a few secrets to himself. For him, dodging the younger sister and the mom on a mission is now sport, with peace and fairness trailing somewhere behind.
