Stoner friends Gideon and Gertrude are baking cupcakes for their school bake sale to avoid failing their Home Economics class. They also bake themselves a batch of weed-laced cupcakes for their own enjoyment. However, they accidentally bring their "Weedcakes" to the bake sale instead. After finding this out, they must work to swap out the Weedcakes with the normal cupcakes before it's too late.
