After questioning his family about important things to consider while seeking his stance, Sammy and his best friend Carl, a cactus wren, leave their desert home, hopping a freight train traveling east. Carl has heard of a great city faraway where folks find whatever they might be seeking. After traveling across vast landscapes, they wind up in New York City. Amid the curious crowds, bright lights, loud city sounds and skyscrapers kissing the clouds, will Sammy find the shape his life should take?
