In the bustling, ordinary world of the Nohara household, a long-held dream quietly takes shape: Hiroshi and Misae have never once shared a honeymoon abroad, and the idea of finally taking one together carries a tender, almost wistful weight.

When Misae stumbles upon an affordable family vacation package to Australia, the destination transforms from a simple dream into an exciting reality for the entire family.

The Noharas set off on what promises to be their first real adventure together, leaving behind the familiar streets of their hometown for sun-soaked horizons and unfamiliar sights. The tone shifts quickly, however, as the trip takes an unexpected turn almost as soon as they arrive.
