By day Griff is an everyday office worker, in an everyday town. He lives a secluded life, bullied by co-workers and his protective brother his only friend. By night Griff assumes his other identity, roaming the dark streets protecting the innocent and the vulnerable from the dangers that lurk in the shadows - he is the hero, Griff the Invisible. Increasingly concerned by Griff’s eccentric behaviour, his brother introduces Griff to Melody an eccentric and charming girl.
