A barbecue is being held in front of a mountain hut. The host, a bus
driver, is celebrating his retirement. He has invited a few women 
with whom he always flirted while driving. The fun-filled celebration
is continually interrupted by dangerous incidents. These challenges
 quicken the pace of relationships in the group.
 An orgy or a spiritual ceremony – anything becomes possible in
 this secluded hut. (imdb)
