Cloud 9 (2008)

Sixty-something seamstress Inge is thrown into a torrid love affair after bringing a pair of pants she altered to their owner, the affable 76-year-old Karl. The problem is she's still in love with her husband of 30 years, Werner, a man whose greatest hobby is listening to recordings of locomotives in the evenings. With the unbridled passion of 20-year-olds, Inge and Karl's explicit trysts cause a rift in Inge's marriage, forcing her to choose between her life-long love and a new infatuation.
