I thought this a cut above the other Silly Symphonies. It starts out as the usual stuff. Pan is a musician, and as he plays, all the forest entities cavort along with him. Once he decides to relax in a tree, a thunder storm takes place and a huge tree is hit by lightning. What ensues is an anthropomorphic fire that attacks all the forest's creatures as well as the trees. Some of the animation is very sad and unsettling. Pan is called on to try to remedy things.
