Zoey, a teenage girl who is heart-broken sits lifelessly in her house and nothing she does seem to make her happy. She is left with no better choice than trying to remind herself what it feels like to be happy. She tries to list out things that make her happy on a simple piece of paper. She is so determined to do so that anything would feel like an obstacle to her happiness, even Sam, her 6-year-old-brother. With pumped up enthusiasm to annoy his sister, him and his buddy, the giraffe doll, fooled around so much that Zoey just couldn't take it anymore. Sensing Zoey’s anger, they scrambled into their secret lair – a fort made out of cardboard. Zoey follows them inside only to realise that something magical proves the fort to be more than just child’s play.
