Wally (Tony Dow) is hired as a weekend lifeguard at Friends Lake. But when he reports for work, his boss regards Wally as too young for the job, and so he is reassigned to sell candy and hot dogs at the concession stand. Meanwhile, Beaver (Jerry Mathers) has been bragging to all of his friends about his brother, the brave lifeguard. When he finally discovers what Wally is really doing, Beaver is not only humiliated -- he's boiling mad! ~ Hal Erickson, Rovi
