Lying has been forbidden in their family for many generations, so one day when these three children lie, their dishonesty makes a big problem for the family. Roham gives a mission to his grandchildren and sends them on an adventurous trip to rescue their parents. On this mission, siblings go along with three dolls, Nargil, Lengeh, and Liveh.
