A ghost resides in the walls, and V must decide if it is an ally or an enemy. The wrong decision could destroy her and her family.

After a hard school year, V goes to her Grandma Jojo's house for the summer to get away from it all. But unlike neurodivergent, artistic, sock-collecting V, Jojo is uptight, critical, and obsessed with her spotless house. She doesn't understand V, and V is sure she's doomed to have the worst summer ever.

Then V starts hearing noises coming from inside the house's walls: knocks, a girl crying, and echoing voices. When she finds a ghostly girl hiding in the walls, they seem to have an immediate connection. This might be V's chance to get back at her perfect grandmother by messing with her just a little bit.
