Irene lives alone on the coastline outside Rome. To her father and her married lover, she’s a student. In reality, she often travels to Mexico where she can legally buy a powerful barbiturate. Working under the name of Miele ("Honey"), her clandestine job is to help terminally-ill people to die with dignity by giving them the drug. One day she supplies a new “client” with a fatal dose, only to find out he’s perfectly healthy but tired of life. Her confrontation with him will call her motivations into question and change her vision of life.
