Tien Pao is all alone in enemy territory. Only a few days before, his family had escaped from the Japanese army, fleeing downriver by boat. Then came the terrible rainstorm. Tien Pao was fast asleep in the little sampan when the boat broke loose from its moorings and drifted right back to the Japanese soldiers. With only his lucky pig for company, Tien Pao must begin a long and dangerous journey in search of his home and family.
