The Better Sister (Season 1)

The Better Sister (2025) is an American crime drama series you can watch online on iFILM, starring Jessica Biel and Elizabeth Banks.

Chloe has the life on paper: Manhattan's elite circles, a sharp lawyer husband named Adam, a teenage son, and the kind of schedule that leaves no room for mess. Her estranged sister Nicky is fighting to stay sober and pay the bills. They barely speak. Then Adam is murdered — brutally, without an obvious reason — and the investigation starts pulling at threads both women wish had stayed buried. The secrets on each side run deeper than anyone expected.

The series works as a whodunit and as a portrait of two sisters whose lives diverged so far they became strangers. Biel plays controlled and careful; Banks plays raw and unpredictable. Together they drive a story that keeps its mystery tight without sacrificing character. Stream The Better Sister (2025) online on iFILM.
