This play is based on Ken Kesey’s famous novel from the sixties. The exciting and humorous story concerns the brutal patient, Randel McMurphy’s attempt to revolt at an American mental institution. The main character is the intelligent, charming and 100% will powered nursing officer, sister Ratched. With all the psychiatric remedies of the sixties – group therapy, electric shocks and frontal lobotomy – she succeeds in the end in rendering him harmless.
