I love the look and feel of this movie. There is not a lot of action, it is more about a tone and feeling. A woman goes missing while on a Mediterranean cruise. Her group of friends (including her boyfriend) attempt to find her. Back on dry land her best friend and boyfriend eventually begin an affair while still searching for her. I've seen this movie a few times and get more out of it each time I watch it.

On a side note, near the end of the movie there are some scenes at a large mansion. If you think current emo (oh, I'm so sad and emotional and fragile) boys in bands with their sideswiped black haircuts are original, check out the artist boy in the mansion scenes in this movie. Remember, this movie came out in 1960. I rest my case.
