With Keling losing his memory of the past, they need to find another way to identify him. As if their task is not difficult enough, one of the petara sets himself to be the prey of a remaung, a deadly spiritual creature of the forest, while the other petara is determined to single-handedly bring down the network of illegal hunting on the land. Pungga, Sampurai, and Laja must race against time to find out which petara is Keling and restore his memory before he loses his life for real to the danger he brings about to himself.
