Paul and Marcy set the screen ablaze in 2002's "Cabin Fever," with a single, fleeting moment of raw, spontaneous passion. There had never been any flutters of romance between them. But circumstances conspired to push this unlikely pair together. When they finally succumbed, their chemistry, while purely physical, was exceptional. But what if the story had played out differently? What if there had been no mysterious outbreak spreading through the woods, no savage dog, no menaces? What if the group's vacation had played out normally? Celebrating the end of their exams, five college students rent a cabin in the woods for a week-long vacation. While Jeff and his girlfriend Marcy do what young, consenting adults do, Paul pursues a romance with his long-time crush, Karen and Bert lurks around the woods hunting squirrels. It is a week of carefree fun and indulgence. But it turns out that even on vacation, mistakes have consequences. Tensions arise and as some relationships break down, new, unforeseen attractions find room to flourish. In an atmosphere of heavy drinking, raging hormones and no rules, who knows where it all might lead? Paul and Marcy's chemistry in "Cabin Fever" was a pure force of nature; a base attraction that overpowered their wits, inhibitions and preconceptions about one another. Cabin Fever: Parting Shot explores how, even without extreme circumstances, nature has an uncanny tendency to take its course.
