I assumed this was a foreign film I found listed in the book 1001 Movies You Must See Before You Die, it was directed by Polish director Jerzy Skolimowski, but it had elements of West German production, but it is a certainly a British set story, and one that sounded interesting. Basically fifteen year old Michael 'Mike' (John Moulder-Brown) has just left school, and finds himself a job at the local swimming pool and public baths, being trained by Susan (BAFTA nominated Jane Asher) who is ten years older than him but he cannot help but find her attractive. He finds that working at the bathhouse has more than just cleaning going on, he is being tipped to provide more services to clients of a more sexual nature, this includes his first lady client (Diana Dors) who is stimulated pushing his face into her bosom and talking about football suggestively, Susan explains that this tipping is normal practice, and that many of the clients ask for the opposite sex for their tips. Mike falls for Susan, despite the fact that she has a fiancé (Christopher Sandford), there is a night when he follows them into the cinema and an adult movie, sitting behind them and him touching her breasts, the fiancé goes to tell the manager and the police are maybe going to question him, but Susan kisses him and is amused, she and the fiancé do not press charges, the police instead allege a minor being allowed into an X rated movie, and the fiancé tries to get revenge before the police intrude. Mike later finds out that Susan is cheating on her fiancé with a swimming instructor (Karl Michael Vogler), who was also Mike's former physical eduction teacher, in jealous anger Mike breaks a fire alarm and cuts his hand, and he is curious to see what is going on between her and the fiancé. So one night he goes to the club he heard she would be, he avoids being spotted and hangs around the erotic area, buying many hot dogs from the salesman (Burt Kwouk), but also he finds a cardboard cutout of a girl, and it looms just like Susan, so he steals it, and hides with leg cast wearing prostitute Beata (Louise Martini) until the coast is clear, and eventually after ages of waiting he confronts Susan on the underground, she neither confirms or denies the image is of her exposing herself. Following a night where Mike swims naked in the swimming pool, with the cardboard cutout, he is angry again and blows the P.E. teacher's car tyres with broken glass, Susan confronts him and they talk in the park, but when she slaps him her diamond from her engagement rings falls into the snow, so he helps her by scooping the area of snow it would have dropped into plastic bags. They take the snow to the public baths, and with the swimming pool drained he lowers the ceiling lamp to use for electricity to connect a kettle and melt the snow, while he continues the melting in the empty pool, she makes the P.E. teacher walk away upset, not just because of the punctured car tyres, but she says that she borrowed the car keys and lost them as well. Mike finds the diamond, and lies naked in the empty swimming pool holding the stone on his tongue, she is given back the diamond and is about to leave, but she undresses as well and lies with him, they talk and make amends, she tries to leave but Mike wants her to stay, unaware they are there the attendant starts filling the swimming pool, and in anger at her trying to leave Mike hits Susan with the lamp in the back of the head, she falls unconscious into the water, he embraces her while they are still naked. I agree with critics, this is one of the strangest films that was made during the Swinging Sixties, it incorporates many of the aspects of the period, especially with the sexuality of the characters, the setting of the dank and grotty bath house is interesting, the acting is as good as you can get, there are some good funny moments, especially during the constant hot dog buying scene, but also the dark and surreal stuff to, but it is all of it's time and a watchable drama. Very good!
