Placid, serene, and tranquil
In media res is when a character is dropped in the middle of action, and that being the beginning of the story.

Episodic plot structures are much like TV show episodes, following a rising action-climax -rising action-climax pattern. I believe the answer you are looking for is Parallel Plot Structure. :)
