Jill Halfpenny is set to star in an upcoming thriller series from Paramount+ – and it sounds gripping. 

Penned by David Turpin (The Ex Wife), Suzanne Cowie (The Serial Killer's Wife), and Nessah Muthy (Grantchester), the six-parter, Baby Doll, is described as a "gripping exploration of trauma, resilience, sisterhood, and the high cost of reclaiming one's life". 

Since an impressive 93 per cent of HELLO! readers revealed that thrillers are their favourite TV and film genre, we think you might want to check out the details below. 

What is Baby Doll about? 

Based on the novel by Hollie Overton, Baby Doll - currently a working title - follows two twin sisters whose lives are turned upside down when one of them is abducted from their quiet countryside town by a local teacher.

The full synopsis reads: "Baby Doll follows the story of twin sisters Lily and Abby, whose lives are shattered when Lily is abducted from their quiet rural English town by beloved local teacher Rick Hansen. After years of abuse in captivity, Lily escapes - only to discover that freedom brings its own challenges. The world she longed to return to has moved on without her.

"As Abby, Lily and their mother Eve struggle to rebuild their family, they must confront the lasting damage and the terrifying reality that Rick is still out there, determined to control the narrative and evade justice. Raw and emotionally charged, Baby Doll is a gripping exploration of trauma, resilience, sisterhood, and the high cost of reclaiming one's life."

Alfie Allen (Game of Thrones, SAS Rogue Heroes) and Jill Halfpenny (The Feud, After the Flood) lead the cast as Rick and Eve, while sisters Tallulah (The Forsyte Saga, My Fault: London) and Delphi Evans will take on the roles of Lily and Abby.
