Leading a secluded life on a remote mountain with his wife KOO SUN-YUET, MIU TIN has taken fifty years to hand carve a few-thousand-step stair-path. Named by their children as the "Flight of Love", it is for his wife's convenience to travel up and down the mountain. Flashback: As a medicinal plant farmer in Two Oxen village, Canton, MIU TIN grew up with CHENG KIU, KWAN KWONG-TAT and LIU SAM-KAN, sharing a fraternity relationship with each other. Ever since his childhood, MIU TIN had already followed his father GRANDPA MIU to gather medicinal herbs on the mountains, getting very familiar with the nature of the species. So in 1934, MIU TIN and the villagers have coordinated their efforts, cultivating valuable medicinal herbs. All of the sudden, the village chief, bringing along his only daughter LAI HO, proposes marriage to MIU TIN. Having learned about LAI HO's real love affection to the poor teacher LAU KA-MING, MIU TIN comes up with a solution. With the intention to stay in mourning for his late parents in the village, MIU TIN entrusts CHENG KIU in transporting and selling the medicinal herbs in the town. However, having learned from the will of his late father that it is not necessary for him to continue bereaving; he then leads all male villagers to deliver the herbs to Canton for sale. SUN-YUET's son SZE-HANG is not willing to go to school because his classmates made fun of the loss of his two front teeth. So SUN-YUET convinces him that the new teeth will soon grow back should the tooth gap be touched by a bride, which is similar to her own experience when she was a bride-to-be. At that time, a boy had stopped her and asked her to touch the gap between his lost teeth.
