Pretty Little Liars (Seasons 1–7)

Pretty Little Liars (2010) — watch online on iFILM. The ABC Family mystery-drama ran for seven seasons and 161 episodes, wrapping in 2017. It is based on Sara Shepard's young adult novel series and stars Lucy Hale, Troian Bellisario, Ashley Benson and Shay Mitchell.

Four former friends — Aria, Spencer, Hanna and Emily — drift apart after their ringleader Alison vanishes. A year later, each one starts receiving texts from someone who signs off as "A." This person knows every secret the girls ever buried. They threaten. They toy. They never show a face. Spencer fights to keep her family's reputation intact. Aria hides a relationship she cannot explain. Hanna buries her insecurities behind a polished image. Emily is figuring out who she is while someone watches her every move.

The show piles on new suspects each season and pulls the rug from under every theory. Janel Parrish's arc as Mona remains one of the most talked-about twists in the whole run. Stream all seasons of Pretty Little Liars online on iFILM.
