Antonio has built a family and a successful career in Milan, far from his mother Angela, a woman of extremes, for better and for worse, irresistible, old-fashioned and hostile, who has come to join him for Christmas. The Christmas Eve dinner thus becomes an emotional, comic and ferocious battleground, bringing a past of misunderstandings back to the surface. The evening turns into a showdown between mother and son that is destined to change the meaning of their bond: a love that burns like a fire within.
