Ellen (Beth Brickell) volunteers to take Mark and his Scout troop on an overnight camping trip when Tom (Dennis Weaver) isn't available. Reluctantly the boys accept Mark's mother to go along with them. When a hurricane threatens to swamp the island where they are camping and Ellen rescues the boys with Ben's help, the boys gain a new appreciation of her.
On their way to see Tom (Dennis Weaver) compete in an air boat race, the jeep with Ellen (Beth Brickell) and Mark (Clint Howard) turns over, pinning Ellen's leg beneath the jeep. Ben, who has followed them, comes to the rescue when Mark is able to get him to pull the jeep off his mother, freeing her leg.
