Greg Heffty and Rowley Jefferson who are best friends live a small town in the middle of the USA. It's the middle of winter and a huge storm goes by.
Greg and Rowley both decide to make a snow fort to stay warm because Greg's mom is making them stay outside. they are almost finished a couple of the neighbor kids show up and destroy the snow fort.
Greg and Rowley deiced to make another snow fort but so do a lot of the other kids in the neighborhood. there ends up being about 15 different snow forts, and eventually ends a snow ball fight between all of them.
The snow ball fight ends because a kid got his tooth knocked out so everyone meets in the middle to discus what to do next. wile this was happening the lower Surrey Street kids sled down the hill. so the upper Surrey street kids make a wall blocking the hill
Eventually the Upper Surrey street kids leave the wall and it turns into a huge free for all snow ball fight between the Upper and Lower Surrey street kids
Since everyone is battling in on the street the snowplow comes and knocks down all of the snow forts and injures most of the kids.
