A man pretends he saves a woman who pretends she's drowning;this person is a former schoolmate's wife ,the secondary school bully who treated him as his punching bag !To become his erstwhile persecutor's wife's lover,what a sweet revenge. But both lovers do not try to hide cause fear is part of the game ,and they carry on openly in public in the cafes ,or in a department store (32 beds to make love!),or in an empty car in a railway station at night (but they are disturbed because the railroad men need to hitch the carriage up to a train leaving ).
