The travel variety show just premieres its 2nd season this December 5, with the cast heading off to Poland for their first trip. The current cast includes Samuel Kim, child actress Ahn Seo Hyun, and 2nd generation children of well-known actors including Hwang Sung Jae, Sun Woo Jin, Sun Woo Chan, and Lee Si Heon. It's unconfirmed whether or not Yu Seon Ho will be joining this current cast, or if he will be heading a brand new group of children for an entirely new trip. 

Meanwhile, 'Nest Escape 2' tells the story of children who leave their homes on a trip overseas without any parental supervision or adult help, for the first time in their lives. It airs every Tuesdays at 8:10 PM KST on tvN.
