Sharon Horgan's 'Bad Sisters' Trailer Sets Up a Murder Mystery With Siblings at the Center

It may be unconventional to let out a laugh during a eulogy for your sister's dead husband, but that doesn't mean it's not fitting. And in Sharon Horgan's Bad Sisters, a laugh over John Paul's (Claes Bang) demise is the nicest thing he may deserve.

A new trailer for the 10-episode dark comedy reveals a personal look at the tight-knight Garvey clan, five sisters who always look out for each other and make ample time to spend with each other and their various partners and children. The show spends time with them both before and after John Paul dies, to get a sense of the deepness of their bond and why they might not all be sad that he is no longer with them. It also dives into an investigation launched by fledgling life insurance agents who are out to prove foul play so they don't have to pay out another claim. As they set their sites on the Garvey sisters, it turns out they all did have reasons to kill him — and they even openly discussed the option with each other.

Horgan stars in the series alongside Anne-Marie Duff, Eva Birthistle, Sarah Greene, Eve Hewson, Bang, Brian Gleeson, Daryl McCormack, Assaad Bouab, and Saise Quinn. 

This is the writer-executive producer-actor's first project from her overall deal with Apple TV+ and is produced by her Merman production company. Other executive producers on the series include Brett Baer and Dave Finkel, who adapted it from the Belgian series titled Clan, which was created by Malin-Sarah Gozin; Merman's Faye Dorn and Clelia Mountford; and Caviar's Gozin, Bert Hamelinck and Michael Sagol. Other writers on the series are Baer, Finkel, Karen Cogan, Ailbhe Keogan, Daniel Cullen, Perrie Balthazar, and Paul Howard. Directors are Dearbhla Walsh, Josephine Bornebusch and Rebecca Gatward. The show hails from Merman Television and ABC Signature.

Bad Sisters premieres Aug. 19 on Apple TV+ with its first two episodes and then one new episode streams each Friday up to and including its finale on Oct. 14.
