Both Max and 99 have a strange dream - 86 is dressed like an movie American Indian Chief; 99 is painted black and white; and their crying child is an alligator! The next day there is an explanation for this as well as other strange dreams experienced by the Chief and the rest of official Washington: they are hallucinations caused by a "miracle drug" discovered by KAOS's "mad pharmacist" Jarvis Pym who threatens to wipe out the government by making the dreams permanent unless he is paid $50 million! Can Agents 86 and 99 stop him?
