How long can you tread water? Matt and Laura's parents build a new swimming pool in the backyard. It's supposed to be a summertime surprise, but as soon as the kids hit the water, a typhoon of terror erupts. Cute pool toys come alive and turn very ugly. Wicked wave after wave threatens to drown innocent swimmers. The calm blue water suddenly changes to a horrible shade of bloody red. Where's a life guard when you need one? Perhaps their strange neighbor, Miss Pincher, will come to the rescue. Or maybe, she's behind all the problems with the pool. Is everyone doomed to dog paddle to certain death? SWIM AT YOUR OWN RISK!!!
