Tonight's presentation of the vintage stage melodrama Gaslight features Cecil (Joe Flaherty) and Cynthia (Andrea Martin), the same couple who appeared in the previous season's "Murder Is Bad for Your Health." On "Sunrise Semester," Angus Crock (Dave Thomas) discusses the subtleties of conversational Scottish. The topic investigated by "Kanadian Korner"'s Bob and Doug McKenzie (Rick Moranis, Thomas) is backpacking with beer on ski trips, you hosers. And Dick Cavett (Moranis) interviews himself. (The U.S. syndicated version of this episode includes material from other SCTV programs, notably "Gordon Lightfoot Sings Every Song Ever Written").
