What fun Barney, Snubby, Roger and Diana are having during their winter holidays! For days on end, the inseparable four glide on skates on the ice of a frozen lake, sled down the mountains, and organize snow battles.

What else can you think if he disappears from his place and... looks into the windows! It seemed? Maybe... Well, did you also imagine ominous sounds in the old house? And where did the mysterious object found in the snow come from? “It’s all one to one,” the guys think and begin to investigate a new mystery.
