Twins Astrid and Apollo are excited to be going to the Hmong July Fourth Soccer Festival, but when they are told to babysit their baby sister, Eliana, it looks like they will miss the particular match their father is interested in--especially as they cannot figure out what the "yummy milk" Eliana demands is, and are forced to spend their money on buying different treats to keep her from throwing a tantrum.

Astrid and Apollo are attending the Hmong New Year festival (which is held at a big arena in St. Paul or Minneapolis in November or December), but in the crowded arena they are soon separated from their parents and younger sister, and between rescuing a little lost boy, and getting mistaken for a pair of famous child singers, the festival turns into quite an adventure for the twins.
