There is more babble than rabble in these proceedings which project an apocalyptic view of the United States and its moribund culture. Vaguely, for more of this is dream than fiction and the ""Continentals"" have taken over all of the disaffected sects -- far right, far left and high middle. In the beginning they stage seemingly innocuous parades with all-purpose slogans like ""Racial Happiness"" or ""A Clean City."" Each parade ends in unprecedented (planned?) disaster. The head of the Continentals, William Star, was sent to an asylum for raping his sister and there fell under the emasculating knives of two Puerto Rican medical students. Turned into a closet queen, he comes out under odd circumstances. While ""straight,"" he pinions large audiences. He's running for president. Daniel O'Dougherty and Dora Dong, freelance writers, hold the key to his past and probable exposure. Both are somewhat understanding in the light of their own previous sexual nightmares, recounted in spurts designed to shock rather than enlighten. The end comes at a Continental Convention where an overstated if somewhat tame hell breaks loose. Given the hand of a satirist, some of this could be funny. Unfortunately Mr. Mirsky bludgeons where he should have stabbed.
