State banquet chef Chen Wuwei received an urgent call from his hometown: his ancestral home was about to be demolished. The only way to save it was to follow his will and join forces with his estranged brother and sister to recover the family secrets scattered across the country. What they hold in their hands is not a treasure map, but an ancestral recipe book called "Flavours of Mountains and Rivers". Every lost famous dish is the password to the thousand-year "taste treasure". When the secret of making soup with boiled cabbage turns into longitude and latitude coordinates, when the lines of antique casseroles point to the emperor's tomb... What they are pursuing are legendary ingredients that are more precious than gold, lost skills, and the truth about family ties buried by time. This is an adventure of measuring the earth with the tip of the tongue and deciphering history with fireworks. They will use the taste they find to ignite the road to rebirth in their homeland.
