Consisting of twelve episodes, Émilie & the Garden Forever is the first part of the romantic, coming-of-age saga Millennial. The premiere season introduces the rowing "crew" team of Riverside Hannah, a private, half day/half board high school situated on the outer bounds of Metro Detroit. Comprised of the team's fifteen most prominent rowers, the main cast is organized into two tiers (primary and secondary).

Set throughout the early weeks of Émilie's first semester of high school, season one takes place in the fall of 2009 over the course of 40 days, tracking all the way starting from the first day of classes to the night Homecoming.
