The transcript of an audio recording of the FBI officers’ arrest and questioning of Winner became public; now Satter has used it, to the letter, as the basis of a movie. It shows us the moment-by-moment situation as Winner, superbly played by Sydney Sweeney, is politely confronted outside her house by the two federal agents. Reality can be stranger than fiction, but ‘Reality’ fuses the two to become stranger, and more riveting, still.
