Zeke hasn't studied for an upcoming science test, so he draws a snowstorm in order to delay the test and get more time to study. However, the storm freezes the entire world, and the unprepared Palmers can neither eat, entertain themselves, nor go outside. Zeke draws the sun to melt the snow, but the differing air temperatures cause a tornado that brings the house to a desert-covered place. To help his family survive, Zeke must use what he learned in science class—in the form of drawings on his Pad.
