But he arrives too late to divert them and one-by-one each member of the family is inadvertently caught as a military prisoner.

Ernie remains at home with Uncle Charley while the rest of the family travel to various locations. Charley invites an old friend to dinner, believing him to be down and out. However, Ernie immediately identifies their guest as a famous television sherriff and he invites the two to the studio.
