Bionicle 3: Web of Shadows is the Annie Award-nominated third Bionicle movie installment. It is also the second movie in the Bionicle timeline, as of 2005. The visuals are completely computer-generated. The events of the movie take place before the end of the film Bionicle 2: Legends of Metru Nui.
The film tells the tale of the heroic Toa Metru returning to their island city home of Metru Nui to rescue its populace the Matoran, all of which remain in a deep coma. But upon arrival, the heroes discover their once beautiful island home has been destroyed and overrun by webs created by spider-like beasts called Visorak, who capture the Toa and poison them, mutating their form into a half-Toa, half-beast state; Toa Hordika. With the aid of the Rahaga, they begin a quest to find the legendary Keetongu in order to find a way to change back into their original Toa forms to rescue the Matoran, who were being held by the monstrous Visorak hordes and their king Sidorak and viceroy Roodaka.
The film begins with the sight of the crystal prison of the Makuta. Suddenly, a mysterious voice calls his name and a talon scratches the prison, causing a small single shard to fall off and land in the Amaja circle from the previous film. Vakama, as a Turaga, begins again the tale of the Toa Metru (from where it left off in the previous film), who sealed the evil Makuta and vowed to save the sleeping Matoran. But the task would not be easy, as the Makuta had called out to his legions, a horde of poisoners led by a ruthless king and a malevolent queen, and the noble Toa must now face a web of shadows.
