History
In the starting of this film, the narrator explains that 5000 years ago, a giant of light protected this particular village from a monster but disappeared after that. One day while returning from a mission, Tsubasa is caught in a sudden storm and encounters a monster. Tsubasa tries to contact Super GUTS headquarters, but a blackhole then suck the both of them in it. The two return to the past, 5000 years ago. Crash landing onto a mountain, the nearby villagers, one of which is a boy named Amu, rescue Tsubasa, but to their horror, afterwards the same monster that attacked Tsubasa attacks the village. On the other hand, a wandering monster hunter stumbles upon the legendary Spark Lance, not knowing what it is she keeps it, but when she approaches the village under attack, the Spark Lance starts to shiver. The village's wooden defenses are no match for the monster and the village is destroyed, with the defenders of the village trying to confront it with spears. It turns out the monster was 'summoned' to this time by a sorcerer who wanted to prevent the revival of Tiga, to destroy the golden pyramid in which he lay petrified (The very same one Daigo enters and discovers Ultraman Tiga in Episode One of Ultraman Tiga).

When Tsubasa sees the Spark Lance in the monster hunter's bag he instantly remembers it looks the same as his father's Spark Lance which transformed his father into Tiga! He takes it away from the monster hunter and transforms into Tiga! The monster is defeated easily but at the end Tiga disappears as his full power is still in the pyramid inside the statue of him, and the whole village is devastated. Later, Amu tells the village he saw the giant of light, but nobody believes him until the defenders state they saw Tiga too. Hearing this, one of the seers in the village claims the prophecy is coming soon and that someone in their village will be the one to awaken Tiga. Despite their triumphing over the first monster, the sorcerer then sends his strongest monster and his two subjects, to attack the pyramid once again. The villagers with help from another village's elits fend of the two minions, but Tsubasa fails to defeat the monster Dogouf, who stuns Tiga with a kick to the face.

Tsubasa reverts to human form, exhausted and the Spark Lance almost trampled by Dogouf nut Amu saves it, and he turns out to be the one who fulfils the prophecy. He uses it to revive Tiga and he himself transforms into Tiga to stop Dougouf, using Tiga Strong Type's finishing move after a tough battle. Tsubasa then fixes his jet and returns to the future, with Tiga watching over the village ever since. Towards the end, the narrator then says: "Thus, this village became known as The Village Of Tiga, and protected it in the years to come, but the memory of this village also became forgotten with the passing of time..."
