Tags: good versus evil

Plot synopsis:
The Mask of Light takes place on a tropical island in the Bionicle universe. According to legend, the Great Spirit Mata Nui created the island's masked Matoran inhabitants. Mata Nui was sent into a coma by his envious spirit brother Makuta, who began a reign of terror on the island until six guardians known as Toa freed the island from his regime. The Matoran, alongside the Toa and Turaga leaders, live in Element-themed regions of the island. The events of The Mask of Light takes place during the latter half of the toyline's 2002–2003 narrative.
The film starts when two Matoran from the fire village of Ta-Koro called Jaller and Takua discover a Great Kanohi, a Toa mask imbued with Elemental power. The two Matoran then participate in a multi-tribal game of Kohlii, the island's national sport: the match reveals developing tensions between the Fire Toa Tahu and the Water Toa Gali. At the end of the match, the Mask is accidentally revealed and the Turaga recognize its powers. They announce that it heralds the arrival of a seventh Toa destined to defeat Makuta and awaken Mata Nui. Jaller and Takua are sent on a quest to find the Seventh Toa, guided by the Mask. In the meantime, Makuta sends three of his Rahkshi "sons" to retrieve the Mask. During an attack on Ta-Koro which destroys the village, Tahu is poisoned, causing him to become increasingly erratic and worsening his already-strained relationship with Gali.
During their journey together, Jaller and Takua receive aid from the Air Toa Lewa, and the Ice Toa Kopaka, the latter of whom temporarily immobilizes the Rakhshi by trapping them in a frozen lake. After this, Takua is threatened by Makuta, and abandons Jaller in an attempt to shield him. Makuta then releases three more Rakhshi, who attack the Earth village of Onu-Koro as Takua arrives. Tahu, Kopaka, Lewa and Gali arrive to help the Earth Toa Onua and the Stone Toa Pohatu: during the battle, Tahu is further corrupted and goes insane, forcing the Toa to capture him and flee. Takua decides to rejoin Jaller, while Gali and the other Toa purge the Rakhshi poison from Tahu, resulting in his reconciliation with Gali.
Arriving at Kini Nui, a great temple at the island's centre, Jaller and Takua are confronted by all six Rahkshi. The six Toa mount a united offensive and defeat five of them, but a surviving Rahkshi attacks Takua. Jaller sacrifices himself to protect Takua, and Jaller's final words prompt Takua to don the Mask of Light: the Mask transforms him into Takanuva, the Toa of Light. Defeating the final Rakhshi, he constructs a craft powered by the worm-like creatures inside the Rahkshi to guide him to Makuta. Traveling to his lair beneath Mata Nui, the two hold a Kohlii contest for the island's fate. At Takanuva's bidding, the Toa, Turaga and Matoran gather together in the chamber, and witness Takanuva merging with Makuta to form a single powerful being. With Takanuva's willpower dominant, the being raises a gate leading deeper beneath the island, through which the gathered people flee. The being also revives Jaller before the gate collapses on top of it. The Turaga proceed to awaken Mata Nui using the Mask of Light, which in turn revives Takanuva. The film ends with Takanuva discovering the long-dormant city of Metru Nui, the Matoran's original home.
