Sam Holt played TV-detective Jack Packard for five years, and he doesn't want to do it again. Not in a movie, not in dinner theater, not even in a commercial for the American Cancer Society. But his tough-minded girlfriend has carried the day, and now he's stuck on an isolated island, hunting clues to a cancer cure alongside Charlie Chan, Miss Marple, and Sherlock Holmes. The script says they're doomed to failure, and when a genuine murder crops up, their sleuthing isn't likely to be much more successful. But with the cops cut off by a storm and a killer stalking the island, Holt and Co. must play detective for real.
