For the past year, Bryan, an airline pilot, has shared an apartment with his friend Philippe. But the latter announces to him one day that he will have to find other accommodation. Philippe can no longer bear, in fact, to see the innumerable conquests of Bryan parade at home. Not to mention that the hot seducer leaves it to his friend to take care of all the chores. Bryan visits a host of apartments and ends up finding one that suits him. However, a young woman is as interested as he is and the owner cannot choose between the two. She therefore offers them a co-location. They accept and, from the first night, Bryan tries to seduce Blandine.
