The five unlikely friends Caroline, Eva, Estelle, Judith and Kiki have been meeting on the first Tuesday of every month for 15 years to gossip and gossip - and once a year they go on a short vacation together. This time, at Eva's suggestion, they want to spend a week of fasting in a remote castle hotel: seven days without everyday life, without stress, without men - and without food. Unfortunately, the meager therapeutic fasting mainly causes ravenous hunger among the women, and the problems at home cannot be shaken off so easily. Empty bellies and sleepless nights soon cause friction. Finally, the real reason for Eva's vacation suggestion turns out: she hopes to find her unknown father at the castle.
