This is the 1981 Horror classic "Don't Go In The Woods" aka "Don't Go In The Woods Alone". No matter what title is attached we pretty much figure that going in the woods, with company or not, may not be such a great idea. 
This was one of the "Video Nasties" that were confiscated and then banned from being sold years back but as time goes on people have mellowed or perhaps forgot how bloody this thing gets so you can now own it without the moral Police knocking on your door. Woo Hoo.
