Old friends reunite for funeral, uncover dark secret

Old school friends Dara, Saoirse, and Robyn reunite for the funeral of their fourth member, Greta, who reportedly died from a fall. Saoirse, a crime writer, quickly suspects foul play when she notices Greta's body lacks a significant occult tattoo shared by the friends. This detail, coupled with a flashback to a disturbing event from twenty years prior involving a burning shack and satanic symbols, fuels their suspicion.

The investigation intensifies as the friends grapple with their shared secret and the fear that Greta's death might be connected to their past. Their reluctant involvement turns into a full-blown caper, involving enigmatic letters, unexpected trips, and a potential assassin. The series, created by Lisa McGee of Derry Girls fame, is characterized by its rapid pace, witty dialogue, and emotional depth, keeping viewers engaged with its intricate plot and strong performances.
