In Montgomery County, Kelly Taylor is ready to go to college and takes her autistic brother, Tom, to a specialized institution. However, the bank informs her that she does not have sufficient funds in her account to honor her check. Her stepfather, Johnny Gaveneau, withdrew the money from her account the day before. When Kelly arrives home, Johnny reveals that he used the money to buy a tiger for his 'safari show' project. In addition he has the house reinforced, in order to protect it from hurricanes, so all the windows and external doors are covered with wood. When Kelly awakes, she finds that the starving tiger is inside the house and Tom and she are trapped with the ravenous animal.
