Fired in disgrace, kids show host Randolph Smiley (Robin Williams) finds himself out on the street, while his replacement Sheldon Mopes (Edward Norton), finds himself on the fast track to success with a new hit show as the proud purple rhino Smoochy. But things take a turn for the worst when Sheldon finds out that some of the people that he works with, and some he doesn't know he's working for, are all in it for the money. Meanwhile, Randolph is slowly turning insane with his only thoughts focusing on killing Smoochy and getting back to his life of luxury.
