Caro hasn't actually been able to do anything for a long time. As a nurse on a dementia ward, she has hardly taken any vacation in the last two years and has accumulated countless hours of overtime. But it is only when her dearest resident, Mrs. Rumi, dies that the barrel overflows: Instead of going to work the next morning, Caro goes to a locker at Frankfurt Central Station, takes out a packed, brand-new rucksack and simply sets off - without a destination, without a plan, without a cell phone and without any outdoor experience.
