“Restless” tells the story of Ling Shi Ying, a reformed juvenile delinquent who discovers she has the power to communicate with the spirits of deceased individuals – the Restless – who cannot leave the earth behind because of unresolved matters in their lives. Reluctant at first to follow in the footsteps of her grandmother – a spiritual medium – Ying gradually finds herself drawn to her new calling. As she helps the restless ones find resolution on earth, Ying makes a discovery of her own through them: her grandmother harbours a dark secret, one that threatens to destroy her … and all those around her.
