This romantic musical takes place in two timelines, in the present day and in the early 1990s. Lili is a singer in her thirties, stuck in all areas of life, who finds old letters from her mother, Eszter. These were written 30 years ago by a man to her mother, who at that time was already planning a future together with her 'perfect fiance in every way'. The letters recall Eszter and her two girlfriends' vacation in Balaton, which takes an unexpected turn when the girls meet a rock band.
