There's just no limit to how far your family will support you, even if it means posing as a primitive tribe from New Guinea. Academy Award-winning actor Richard Dreyfuss stars as a harried anthropologist who calls upon his eclectic family to pose as a lost-world tribe in order for him to win a new grant. All he has to do is get his clan to dress up in costumes and romp around in the backyard, acting like the natives they're supposed to be. When a rival starts snooping around, Richard has to step up his efforts or lose everything. Lily Tomlin and Jenna Elfman costar in this quirky family comedy.
