After eating the seeds of a strange-looking bush, Gilligan (Bob Denver) suddenly develops the ability to read other people's minds. At first, the Castaways are amazed and delighted by Gilligan's new-found psychic talents. Inevitably, however, Gilligan reveals far too much of what's on everybody's mind--proving yet again that, in the world of situation comedy, honesty in NOT always the best policy!
