The Rubbles are forced to move in with Fred and Wilma while a plumber fixes Fred's "repair job," which did far more harm than the Rubbles' original problem. What began as a simple leak ends up becoming a very major, week-long plumbing job. During the Rubbles' stay, Barney causes so many problems for Fred that he finally loses his patience and blows his top with Barney. Meanwhile, Wilma is angry at Betty and begins to fight with her. After Fred and Barney overhear Wilma and Betty fighting, they stop fighting, make up, and get the wives to also make up, leaving everything correct again between both the Flintstones and the Rubbles.
