Old Guys in Bed (1970)

Paul, a lonely 60-year-old man, falls in love with Bill, a Hungarian immigrant ten years his senior, whom he met on the web. The connection is immediate, and the two elders quickly develop a passionate virtual love affair, even before they meet. But from one day to the next, Bill abruptly stops responding to his companion, systematically refusing all his calls and messages. Distraught, Paul tries everything he can to get answers to his questions and to put the pieces of his broken heart back together again.
