The friends Alexandra, Edvin, Dushan and Tindra have graduated from the sixth grade and are looking forward to a long summer holiday with lots of swimming and adventure. Tindra's birthday is to be celebrated and the friends have big plans. But in each direction they all go through different difficulties and nothing turns out as they have imagined. Instead, the holiday looks like it will be a total disaster. Summer before seven is a continuation of Summer before six and is about friendship, love, empathy and courage.
