Dirk Bogarde portrays a philosophy professor at Oxford, contentedly married with two children and another one expected. He has a preferred student—Michael York—who is interested in a new arrival, the attractive Austrian Jacqueline Sassard. They share Sunday meals with Stanley Baker, a colleague also teaching at the university who’s dealing with problems in his marriage as well as feeling resentful of his rising profile on television. It's essentially an intellectual entanglement; Bogarde finds himself drawn to his student, but she seems interested in both York and Baker too. Even indulging in plentiful alcohol during these meals doesn’t improve things much. The film misses any real sense of excitement or complexity—it simply offers a look at the bored, pretentious upper-middle class that ultimately only underscores how superficial the characters developed by Nicholas Mosley are, a quality not significantly improved by Harold Pinter's involvement. While the acting is commendable, particularly Baker’s performance, there isn’t enough material to create any genuine interest.
