In order to develop new drugs, a hunter (played by William Dafu) is commissioned by Red Leaf Pharmaceutical Company to embark on a journey to capture the endangered Tasmanian tiger, lodging in a family of three whose male owner has been missing for half a year on the magnificent Tasmanian plain. While hunting painstakingly, the hunter gradually fell in love with the hostess and two children, witnessed the serious environmental crisis in the Tasmanian Plain, uncovered the mystery of the man's disappearance, found the trail of the Tasmanian tiger, and inferred the various interests behind the scenes, so the hired hunter stopped hunting and began to pay attention to the orphans and widows. Exasperated by the interests behind the scenes, what will happen to the new hunters, hunters and a family of three, as well as the endangered Tasmanian tiger?
