Eighteen (2020)

When Sophie arrives home from a disappointing holiday to France after her A Levels, she soon learns that her best friend, Anna, has had the summer of her dreams without her and replaced her with a mystery boy, Ollie, who seems too good to be true. Yet, confusion and chaos at a friend's party in the evening exposes his true nature, forcing the girls to acknowledge that their love for each other is far more powerful than a fleeting summer romance.
