Plot
As a kid, he wanted to be a policeman to put his own father in jail not just for the crimes he's committed, but also for hurting his mother. For good things happen to those with pure intentions, he meets Ruth —a beautiful lady who will later on give him a son. They marry each other even without the blessings of Ruth's mother. But sometimes, fate has a way of playing with people's lives. One of the criminals Gabriel busted years ago manages to escape the prison. To have his revenge, the criminal goes after that which matters most to Gabriel-his family. Now, Gabriel finds himself fighting for his life and that of his wife and son. After five years of suffering from amnesia, Gabriel recalls everything but it's too late. His wife is already married to his former suitor. He realizes that she does not intend to return to him. How ironic that he's regained his memory only to find out that he's already lost everything he cares for. And so he decides to look for his son. He strongly believes that he is still alive. And he is right. For his son now lives with the Ungtas in the island of Noah—a world completely different and unknown to men. But Ruth is also just pretending that she's forgotten the tragedy that took her son away and changed their lives. She still holds grunge for Gabriel for allowing his job to put their family in danger. Meanwhile, Eli welcomes his 7th birthday with disappointment as he wakes up without a tail. He has anticipated it since he was younger. With such sadness on Eli's eyes, Adah can't find the strength to tell him the truth for she knows it will bring the child more pain. But Eli finds something in the forest that might give him an explanation on he really is — a toy soldier. He trains day and night to regain his strength. Not long after that, Gabriel finds himself in a police station again... as a police officer. This way, it will be easier for him to find his son Jacob. Meanwhile, Eli continues to seek the creatures that look like him. He asks around trying to gather information and follows the colorful bird that flies in and out of Noah hoping to get a lead. Eli fails to reach the riverbank leading to the sea where he believes he can find others that look like him. So he, together with his best friend Lotlot, escapes on that night to follow the bird. He has no idea about the danger that's about to come his way for his Uncle Caleb releases the buwa-buwas to sabotage his brother's reign. At the near end of this, Gabriel shoots Judah, although before Judah dies, he shoots Gabriel and Gabriel slowly dies. Before he dies, he puts all of Isla Noah and the world back to normal. After, Gabriel dies, although, the Diwata lets him go back to life and Gabriel and Ruth are happily married.
