Me and My Shadow reveals the once secret world of shadows and their human counterparts. Stan (Bill Hader), our hero's shadow, yearns for a more exciting life but happens to be stuck with Stanley Grubb (Josh Gad), a timid guy with an extreme aversion to adventure. When a crime in the shadow world puts both of their lives in danger, Stan is forced to take control of Stanley. They go on a madcap adventure to investigate the crime and stop the shadow villain from leading a rebellion where shadows take over the human world. During this adventure, Stan empowers Stanley to let go of his fears and embrace life. Through their adventure, they both learn that one cannot be whole without a true friend.
