Lucy is a modest nun who has not left the walls of the monastery for 20 years. And everything would be as usual... if not for one "but": her first love is accused of a crime he did not commit. To save him, Lucy will have to break her vows... and a few laws. Everything is complicated by the fact that she has completely fallen out of reality: the world outside the gates has changed a long time ago. Now she is waiting for a crazy journey - with eccentric companions, comical situations and very earthly temptations. And at the same time - a chance to learn the truth about the same night 20 years ago, when she left everything and became a nun.
