With only five days to scrape together the money to get home, he receives unexpected help from a young boy named Jun and the unsuspecting townspeople who have fallen in love with his culinary talents. With a makeshift food stall set up by his new friends, he begins cooking and selling Taiwanese noodle soup in front of the local Buddhist temple. Misfortune befalls the unlikely troupe when a drug dealer tracks down Jun's mother - a former addict - and through her, Mr. Long. But despite the inevitable confrontation with his violent past, Mr. Long will find it hard to give up his new life.
