Cabin Fever (15)

Five friends, Jeff, Marcy, Paul, Karen and Burt, head to a remote cabin for the weekend. Burt takes his trusty rifle and heads into the woods to pretend he is playing one of his violent videogames. He accidentally shoots a local man, Henry, who is infected with a flesh-eating virus. One of the students unwittingly drinks water which has become contaminated with the virus. The remaining out-of-towners become embroiled in a fight for their lives against the deadly contagion.
