Enteng is a gym assistant who lives with his mother, Belen, sister Mara and brother, and has a crush on a local schoolteacher named Cielo.
The first of them is Utoy, a vagrant who is lynched and dumped next to a meteorite fragment next to a pile of rats who transforms into a mutant called Dagampatay.
After an attempt to poison the La Mesa Reservoir, he is defeated by Captain Barbell when he boomerangs his spit back into himself, dissolving him.
The main villain is Lagablab, formerly Enteng's father Arnaldo, a fire-breather at a circus who went on the run after killing his employer and getting struck by lightning, gaining pyrokinetic abilities.
[3] Actor Albert Martinez was hospitalized for a few days after accidentally swallowing kerosene during the filming of a fire-spitting scene, which he insisted on doing himself instead of his stunt double.
