Bloom Up is the true story of Hermes and Betta, an Italian couple who have been exchanging for over 4 years. The docufilm highlights their daily life on the one hand: at work, at home, their daughter and interests; and the attraction for the swinging world and its practice on the other: meetings, parties, dinners, car sex and much more. Everything is told and shown "without filters". The camera "pawns" the two main characters within a "perverse" world sweetened by the sweetened gentle soul of the couple.
