What is the series all about?
The trailer for the limited thriller series The Better Sister was released on April 30, 2025, and is available on the official Amazon Prime Video YouTube channel. It begins with Chloe Taylor doing her makeup and recounting that her husband, Adam, was murdered, and her sister, Nicky Macintosh, has arrived to stay with her.
Chloe is shown in a frustrated and anxious state before the clip cuts to a car driving along a coastal road at night. A detective in charge of the case tries to help her recall what happened on the night of her husband's murder. She then informs Chloe that her husband's death was staged to look like an accident.
After her sister Nicky arrives to meet her upon hearing the news, it is revealed to the audience that Nicky is Ethan's biological mother. Nicky is also declared mentally unstable and viewers learn that Adam was romantically involved with her before marrying Chloe and settling down.
The investigation later reveals that the alarm was turned off 20 minutes before Adam was killed. The police then start suspecting Ethan, who is considered a primary suspect in his father's murder.
Now, after all these years, the sisters reunite to help their son out of trouble, as they consult a lawyer together about the case. However, things don't go smoothly, as Chloe accuses Nicky of having a miserable life because of her bad decisions, Nicky retaliates by stating that her whole life has been a lie.
Meanwhile, Detective Matt continues investigating Chloe and warns her that a killer is still on the loose. The trailer ends with the sisters heading towards court, surrounded by the media.
