In the last edition of the LISB-ON electronic music festival, something strange happened there as people suddenly started to see grass and plants growing from and taking root in their heads, as a result of their musical experience in permanent contact with nature. This group of people then realised they needed to look for someone to take care of their heads and in Lisbon they discovered a barber who had adapted new techniques and a set of new work tools like pruning shears, rakes and a leaf vacuum sweeper among others, in order to become a real hair gardener. And this is the story, created around this phenomenon and the odyssey experienced by this group of people which is narrated in a film by the barber himself, in the tone and register of a fictionalized documentary.
