Two sisters, Anna and Melina spend the last days of the summer in their vacation house outside of Athens. Anna is having a party to celebrate her birthday and her passage to adulthood. Soon she will be off to college leaving her little sister behind. She has invited Maria, her crush, to spend the day with her by the pool and organise the party.
Melina obsessively loves and admires her older sister and wants badly to be part of her world. She is not invited to the party. But she sets her mind to it, making this night for her sister a bloody night to remember.
