One day Helen wakes up and it's SPRING! The snow has melted and the sun is shining. But Helen knows that the blackflies will be coming out soon. So she does what any smart kid would do: she sends her little sister outdoors to check! When the blackflies and mosquitoes carry her away, Helen tells her dad, who rushes outside and is carried away himself. Now Helen needs to rescue BOTH of them, along with a wolf and a very clever bear.
