Freya, Carla and Sussi, after a night of partying, walk back home together while the conversation takes an unexpected turn: their sex lives, marked by dissatisfaction and frustration. Whether they are in a couple or single, nothing seems to work, and the confessions that emerge between laughter and honesty lead them to question whether the problem lies within themselves.

“Must be me" is an honest, raw and funny exploration of intimacy, self-acceptance and the power of friendship as they discover that maybe they weren’t the ones to blame after all.
