The surgeon Diego Mancini moves to Puglia where he falls in love with Elena, a woman who is divorcing and who has a daughter, Anna. Together they have a child, Paolo, and when the divorce is complete and they are about to get married, the child is diagnosed with heart disease. The only hope of salvation is a transplant, but there is already a girl on the list, and she is at the crossroads. Diego’s priority is to save his son at all costs, even at the cost of betraying the oath linked to his profession. He thus becomes the doctor of a fugitive boss, putting his family in danger and slipping into a whirlwind of blackmail.
