The Voyage (Il viaggio)

When her husband, Antonio Braggi (Ian Bannen), is killed in a car accident, the beautiful Adriana (Sophia Loren) undergoes a period of mourning. But things get complicated when Antonio's brother, Cesare (Richard Burton), who once loved Adriana but stepped aside, starts wooing the widow. Then she falls ill, and a doctor discovers the reason -- an incurable disease. With their time together quickly running out, Cesare and Adriana must choose whether propriety is more important than being happy.
