The Better Sister on Prime Video is an eight-part twisty-turny thriller that promises to keep us on the edge of our seats until the final moments.

The series is based on the novel by bestselling author Alafair Burke and stars Hollywood favourites Jessica Biel and Elizabeth Banks as 'rival' siblings who have their mysterious past brought to light after a shocking murder. But, as the investigation unfolds, will the siblings manage to reconnect or be torn further apart?

Here is everything that happened in episode 2...

The second episode opens with a flashback of Chloe and Nicky when they were little and playing by a lake. Chloe almost accidentally drowns, and her father saves her.

The episode returns to the present day, and it is the morning after Nicky arrived in New York. Chloe hates her being there and seeing that she is getting on with Ethan. Chloe heads to the office, which seems odd just after her husband has been murdered, and Nicky tries to be nice to her sister by complimenting her on her lipstick. Chloe tells Ethan she hates leaving him, but has a few things to do at work and that they will have a nice dinner that evening - again, slightly odd after Adam's just been murdered.
