The film essentially follows its predecessor, by placing the 1970s Brady Bunch family in a contemporary 1990s setting, where much of the humor is derived from the resulting culture clash and the utter lack of awareness they show toward their relatively unusual lifestyle.
One evening a man claiming to be Carol's long-lost first husband Roy Martin, shows up at the suburban Brady residence.
Mike has been planning a surprise second wedding/renewal of vows for himself and Carol for their anniversary present, and Roy's arrival throws the Bradys into chaos.
Peter, who is trying to decide on a career path, begins to idolize and emulate Roy which gets him into trouble at the architecture firm where Mike works.
Peter later mentions Roy talking about "the big house" and Mike, who learns that it means prison, starts becoming suspicious.
Upon finding it, they stumble upon a photograph revealing the truth about Roy: he is actually a conman named Trevor Thomas, there to steal a familiar horse statue that is actually an ancient artifact worth $20 million.
It turns out Trevor was responsible for the boating accident that led to the disappearance of Dr. Whitehead's son Gilligan and Carol's first husband, a professor.
As Mike and Carol renew their vows in a ceremony held at their home, Marcia agrees to let Greg have the attic to himself until he goes to college, and the two share one last on-screen kiss before returning to being brother and sister.
[12] Mick LaSalle of the San Francisco Chronicle instead found the film not as fresh as the original, opining that while the subplots with the Brady children are bold and funny, the main plot failed to exploit its comedic possibilities.
He still found it overall enjoyable enough to satisfy those who liked the first film, and commented that "As a satire of a sitcom that wasn't funny, it's often at its funniest when it's purposely stale.
"[13] Beginning in the mid-2010s, the moment where Marcia Brady (portrayed by Christine Taylor) says "Sure, Jan" became an internet meme, usually in the form of a response gif.
In the original scene, while the Brady family is at the dinner table, Marcia questions Jan about her "boyfriend" George Glass.
