Answer:
Plot
Step-by-step explanation:
The theme is the main idea of the whole text. A plot, on the other hand, can be defined as: "the main events of a play, novel, movie, or similar work, devised and presented by the writer as an interrelated sequence."
In this case, there's a clear sequence. There's a beginning, a middle, and an end. Although it very general and can be fit in many stories and even movies (such as Predator), the fact that we're talking about one specific man who becomes hunted until rises again as a hunter, creates a clear timeline of events that characterize this as a plot.
