Like the original series, "Pretty Little Liars: Original Girls" brings together five new teenage girls living in a small town — this time Millwood, not Rosewood — who have to band together to protect themselves from a stalker called A.
Imogen Adams, played by 22-year-old actor Bailee Madison, is the leader of the group and a pregnant high school student.
While Imogen's age is never stated, it is likely she is between the ages of 15 and 17 since she doesn't seem new to the school, nor does she talk about college or graduating.
