Sam and Janet

Sam and Janet prepare to set off for a wine-and-cheese party, though discover after setting off that they have lost the host's invitation that they do not know the address of the party.

Sam and Janet get caught in the crossfire for once as their son Peter drops out of college to travel the world with his new acquaintance Ron, a fully paid-up member of the alternative society. Janet and her daughter Patsy, however, concoct a plan to sabotage Peter's plans. Sam, too, is almost persuaded by Ron's idealism until he is brought back to earth with a bump.
