Lanchang Kuning.

To seek revenge on a woman whom doesn't reciprocate his love, Dato Ali lies to the Sultan that misfortune will befall him and his kingdom if a sacrificial ritual is not performed. The Sultan believes him and orders that the sacrificial ritual be carried out, without knowing that it involves the use of blood from a woman in her first pregnancy on the sail boat 'Lancang Kuning' before its maiden voyage.
