VOLUNTEER is a film about the grassroots movement of ordinary Swiss citizens who set out to help thousands of refugees stranded in Greece. In rich and safe Switzerland, citizens from different backgrounds leave their orderly lives behind to support people in need. There is a Swiss farmer and his wife who raise cows in the Alps, a captain in the Swiss army, a pensioner who resides on the lakeside, and a successful comedian and entertainer. These volunteers embark on an adventure that will change their lives forever.
