The movie's main theme is adultery

As a woman puts away her luggage before a train ride, we see a man stare at her backside with lust.

A man and woman go for a swim in their underwear in the hotel pool. When the woman gets out, her clothing is wet, and the shape of her butt is shown through the clothing. Sam watches in awe and leans over the edge of the pool.

Soon afterwords, they go back to her hotel room, and he pushes her up against the wall and kisses her. He then throws her onto the bed, rips off her dress and his shirt. They passionately make out on the bed. The scene ends there. They wake up together the next morning and it comes out they had sex twice.

The morning after, they lie naked in bed. As the woman fetches her clothes, we see the top part of her right buttcheek.
