Red Rose | Preview (BBC Three)

The story follows a disparate group of teenagers, adrift in the long hot summer following GCSEs, hanging out on the Bolton moors with little sense of direction or purpose now that school is over.

Rumours circulate of the Red Rose app, an urban legend that blooms on the smartphones of teenagers, encouraging them to undertake a series of challenges increasingly dangerous in its demands.

On the fringes of her group of friends, Rochelle Jackson downloads the mysterious app, naively inviting darkness into her life.

What she sets in motion is a series of events that take the town by storm, and bring the friends together to battle the unseen forces of a seemingly supernatural entity.

Red Rose will explore the precarious relationship between teenagers and their online lives, the seductive power of what is not real versus what is and often less exciting; but ultimately it is a story of friendship told through the prism of a classic horror-thriller.

Red Rose begins Monday 15th August on BBC Three.
