Henry IV is a tragi-comic play about an actor who fell off his horse while playing the part of Henry IV, and consequently has spent the last 20 years believing that he really is Henry. His entire life has been organized so as not to upset this fantasy; however, when his nephew brings a doctor to meet Henry in an attempt to cure him, the occupants of Henry's castle discover that all is not as it seems. The play deals with themes of reality, madness, masquerades, and identity.
