In the mountainous countryside on the island of Mindanao in the Philippines, a small rural community is shocked by the death of local farmer, Albert Moreno. His death is attributed to an accidental drug overdose. Knowing his father's hatred of drugs, Albert's son, Enyo believes that his father was murdered, especially after learning that, shortly before he died, Albert had discovered a secret tunnel on his farm that could possibly have been used as a hiding place for some of the legendary Yamashita's Gold. Together with his girlfriend, Geri and his father's oldest friend, Bong Velasco, Enyo sets out to prove that his father's death was no accident and to bring his killers to justice.
