Cleveland makes two huge discoveries in his personal life. First, he finds out that Donna never legally divorced her ex-husband, so she and Cleveland are not legally married. Then, he discovers that his best friend Terry is gay and has been dating a guy named Paul. In light of these new developments, Cleveland, Donna, Terry and Paul decide to go to Vermont and have a double wedding ceremony. Meanwhile, Cleveland Jr. tries to help Rallo break a nasty habit.
