Do we have the right to end our lives if life itself becomes unbearable, or when we enter the late-stages of painful, terminal illness? FRONTLINE offers a revealing look at people facing the most difficult decision of their lives.

Do we have the right to end our lives if life itself becomes unbearable, or when we enter the late-stages of painful, terminal illness? These questions, debated for centuries, have only grown more pressing in recent years as medical technology has allowed us to live longer lives, and several U.S. states have legalized physician-assisted suicide. With unique access to Dignitas, the Swiss non-profit that has helped more than 1,000 people die since 1998, Academy Award-winning filmmaker John Zaritsky offers a revealing look at a couple facing the most difficult decision of their lives — and lets us see for ourselves — as one Chicago native makes the trip to Switzerland for what will become the last day of his life.
