Some days turn out to be simply unforgettable. For Marie, it all starts with a pregnancy test… that proves positive, a car accident and being fired from her job... For Hortense, mobile phone in hand, the frantic quest for sexual satisfaction begins in a traffic jam... For both Luis and Maurice, the unexpected appearance of a loved one pitches them into a world of dreams and nightmares. While some of the characters know each other, others come into contact by chance. One woman profits from all this, the other is shattered. One will have gone looking for trouble, the other will have asked for nothing. There'll be no fatalities.
Unfortunately the movie A Hell of a Day is not yet available on HBO Max.
