Following his wife's untimely death, Los Angeles journalist Benjamin Mee (Matt Damon) decides to make a fresh start by quitting his job and moving his children (Colin Ford, Maggie Elizabeth Jones) to an 18-acre property containing the Rosemoor Wildlife Park. Though closed for years, Rosemoor is still home to many animals, cared for by Kelly Foster (Scarlett Johansson) and her small staff. Mee opens his heart and his checkbook as he, Kelly and the others work to renovate and reopen the zoo.
