 Young Dr. Kildare is still being trained at General Hospital by old, crusty Dr. Gillespie. This time, he tries to rehabilitate Gregory Lane, a brain surgeon depressed over losing too many patients (and incidentally Kildare s romantic rival for nurse Mary Lamont). Lane s losing streak takes a new turn when one of his patients survives...but seems to be insane. Or is the man s strange obsession with Friday the clue to a mystery? To find out, Kildare must take a terrible risk.
