A slapstick comedy that returns to the simple, laughable style of the TV series. The Nohara family plans an extravagant yakiniku dinner, but they are suddenly placed on a wanted list by the mysterious organization Sweet Boys. To avoid capture, the family must flee from Sweet Boys’ pursuit, yet they still want to enjoy their dinner. The only way to satisfy their craving is to halt their escape and confront Sweet Boys’ boss, who operates out of Atami, a hot‑spring resort city in Shizuoka Prefecture.
