Luke travels on the overnight train from Hanoi to Sapa high in the hills and meets and learns all about the lifestyles of the ethnic minorities. Luke visited Sapa high in the hills in northern Vietnam 15 years ago. He’s pleased to find out that not much has changed and visits a little girl he befriended during that time. She welcomes him into her house and learns how the local dish of dried buffalo is made. He also goes foraging for botanicals with a scientist who is making Vietnam's very first gin.
