Middle schooler Yuna, born in America to Korean parents, struggles with feeling too Korean to fit in with her American peers at school. Frustrated with her fractured life and desperate to fit in, Yuna makes a wish on paper stars to return to Korea so she might feel normal somewhere. When the unexpected death of her halmoni (grandmother) makes Yuna's wish come true, Yuna is wracked with guilt and feels more fragile than ever as she realizes she also feels too American to fit in with her extended Korean family. As her family prepares to bury her halmoni, Yuna has to race the clock to fold more stars and undo her wish before her halmoni is gone forever.
