Hard to talk about this work without revealing something capital. Let's say it's about falling in love and learning to get over it. On a cruise ship. a young man, "A", (Gad Elmaleh) confides to an old couple about his recent short love affair with a young woman, "Pollux" (Cécile de France) which ended abruptly.
The awkward and shy A meets the outgoing and lively Pollux. His thoughts ("A" narrates the story) during the affair are very humorous and typical of the guy who's too shy to go further and wouldn't have if it had not been for the girl who does all the right moves, something he could only dream of and never got before.
The truth about the abrupt ending of the relationship comes later, as a shock. The hero eventually learns how, as they say, to get a life. A superb, simple yet effective and memorable movie with two underrated young actors.
