This part introduces the title and shows a snippet of the setting of the movie and gives the audience and idea of what might happen in the movie. Also the title was chosen by the effect of every year the town they are living in creates something horrible.
This section shows who the main characters are and in this case they are Sophie and Gerald and it also shows more of what the setting is just in another perspective. We can also see they are both sad so that means something has happened. The town as you can probably rather large and it is called Carding.
In this section the splashes are the problem of the story and that is why they are crying and they are also crying in the section before because the sunset makes something bad happen ever year so there showing there love for each other incase something goes wrong and in this case something does.
