杜立德(艾迪·墨菲 Eddie Murphy 饰)因为拥有能够和动物交流的特殊能力而在当地名声大噪,拜访他的除了人类以外,前来寻求帮助的动物亦是络绎不绝,一时间,杜立德忙的焦头烂额,在无形之中忽略了家人们的感受。
一天,一群动物找到了杜立德,它们赖以生存的森林即将被砍伐,它们希望杜立德能够帮助它们保护唯一的家园。杜立德在森林里找到了珍稀物种太平洋熊艾娃(莉莎·库卓 Lisa Kudrow 配音),只要能给艾娃觅得一配偶,那么就可以要求政府保护这片森林。在马戏团里,杜立德找来了早已经被人类驯化的大熊阿奇(史蒂夫·茨恩 Steve Zahn 配音),但很显然,阿奇并没能够吸引到艾娃的注意。
Aston (Robert Shaw), a quiet, reserved man, lives alone in a top-floor cluttered room of a small abandoned house in a poor London district. He befriends and takes in Mac Davies (Donald Pleasence), an old derelict who has been fired from a menial job in a café. In time Aston offers him a job as caretaker of the house. Aston's brother, Mick (Alan Bates) - a taunting, quasi-sadist - harasses the derelict when his brother is away, countermanding his orders. Eventually Aston, himself irritated by the cantankerous old man, puts him out.
