In a small Lancashire town, two lives intersect with secrets buried deep within a century-old mill.

After serving in the Gulf War, Dev opens a bakery in an abandoned wallpaper mill, seeking peace and purpose. Meanwhile, Dani, haunted by her family's troubled history, leaves Manchester and moves in with her grandmother, whose own past is tied to a scandal at the mill dating back to 1915.

As Dani and Dev grow closer, they uncover dark secrets that link Dani's family to the mill. A hidden room within its walls holds answers to long-buried mysteries, from a love affair with a spy to a shocking betrayal. As events unfold, Dani must confront her own buried guilt, while Dev faces his unfulfilled feelings.

When past and present collide, can Dani and Dev find peace, or will history's sins consume them?
