The Plot describes the events that make up a story or the main part of a story. These events relate to each other in a pattern or a sequence.
Here we introduce the Protagonist and his happy life. Soon his happy life becomes problem some. Then we introduce the Antagonist, who makes to make sure this disturbance never leaves the Protagonist. We dictate how the Antagonist will keep the Protagonist under his thumb and either destroys his happiness or even his life. Make note of who the Protagonist can call on in their time of trouble. Will it be a friend, a stranger become an Ally? Will a love interest change his life direction, views or/and bring motivation for the Protagonist to make change.
