Walking Under Water: In the crystal clear waters off the coast of Borneo, a unique way of life threatens to disappear forever. For generations, the Badjao were oceanic nomads, living in harmony with the sea as fishermen and free divers. Nowadays, however, only a few Badjao remain, like Alexan, who still remembers the old ways. He hopes to pass his knowledge along to his ten-year-old nephew Sari, but time and opportunities are running out. Sari loves the sea, but it can only offer a hard life of subsistence fishing, while the nearby tourist resort sings a siren song of easy money.
