Browning is a PI with a bad cold, who's sent to investigate a case by a mysterious client. He stumbles across the body of a young woman and is stabbed to death, and when he wakes up in heaven, they tell him he's "marginal material," and they can only decide on his final destination through one last assignment: to go back and solve his own murder. As a dog. A cute fluffy little dog (Benji). Undaunted, Browning begins to investigate the case as best he can around his canine disabilities (dialing the phone presents a special challenge) to solve the murders, save the girl, and see justice done.

While on a publicity tour in Switzerland, Benji, Cindy Smith, and Patsy Garrett convince Kris Kringle that his place on Christmas Eve is delivering presents to all "his" families all over the world.

Benji is a stray who has nonetheless worked his way into the hearts of a number of the townspeople, who give him food and attention whenever he stops by. His particular favorites are a pair of children who feed and play with him against the wishes of their parents. When the children are kidnapped, however, the parents and the police are at a loss to find them. Only Benji can track them down, but will he be in time? If he can save the day, he may just find the permanent home he's been longing for.

Some school kids stumble across a briefcase full of money, when they go back for it, they find a body instead. When they bring the police, neither is there, and the police refuses to believe them. Later they discover both were part of an assassination plot. Now they have to figure out how to stop the plot and put the bad guys in jail.

Benji gets lost after a flight overseas and becomes a stray in Athens, Greece. He then tries everyday to reunite with his family while mysterious people pursue him, in a race to get a code which was secretly tattooed on his paw at the airport. But who are the bad guys and who are the agents that can be trusted? Will Benji and his kids and their nanny ever get to enjoy their vacation?

迪士尼于1987年发行了一部十分特別的电影，全片几乎都是由动物所主演，片名是《丛林赤子心》（Benji the Hunted），故事內容是敘述一只名叫Benji小狗的故事。 其實在《丛林赤子心》之前，导演Joe Camp所属的 Mulberry Square制片公司已在1974年、1977年、1980年推出了三部以小狗Benji为主角的电影，都受到观众的欢迎，1987年的《丛林赤子心》才是与迪士尼合作，再度介绍这只传奇的灵犬！ 本片剧情是叙述灵犬Benji流落野外的故事，Benji发现有一只豹妈妈被猎人射杀，留下孤苦无依的四只小豹，Benji在恻隐之心的驱使下，顾不得自己远离家园，还担负起照顾四只小豹的任务，甚至因此放弃了好几回它明明可以回家的机会。另外，Benji还要提防灰狼等凶猛野兽的攻击，保护小豹的安全。最后，它总算替小豹们找到了一个适当的归宿。 本片的导演是Joe Camp，本片大部分情节都是动物们演出的画面，因此有对白的部分并不多，故事情节相当感人，配乐也非常不错 ，本片的配乐则是由Euel Box所负责。
