Shadow River

Peter and his wife Susie, enjoy camping.
Peter has decided that it would be great to camp on a houseboat, and has just won an Auction on Ebay, of a rundown houseboat, at a bargain price.
Susie does not like the idea but decides to go along with it.
A few days later, they meet up with the owner, Mark, on-site, to finalize purchase and camp nearby; wanting, to get the feel of the area.
In a matter of hours, Susie is missing.
Peter soon finds out that the houseboat and Shadow River, has a horrific past and is desperate to find Susie before morning.
