Amanda Lemmon is a 9-year-old orphan, and she is about to be adopted by the Butkises, a family known to collect kids. While at summer camp, Amanda meets an identical girl named Alyssa Callaway, who has come home from boarding school, only to find that her wealthy father, Roger, the camp’s owner, is about to marry Clarice Kensington, an overbearing self-centered gold-digging socialite.
