Just that. Like any Christie masterpiece, it's a total guessing game with a frustrating lack of answers for its hapless cast of characters. Essentially, ten people find themselves on an island with a record that accuses them individually of varying crimes. They get knocked off successively with an ending that, while not in keeping with Agatha's original story due to the dictation of the Hayes code, is still a "wow" moment. It's similarities to Identity (2002) can't be ignored, but that doesn't mean by any respect that the latter isn't a great movie or even derivative, managing to devise new and smart connections between the characters as reasons for them all to be held down and picked off, one by one.
