As a qualified Engineer, Phil Avery moves into teaching at his local ‎further education college. Despite his best efforts to prepare his ‎students for future roles in construction and trying to maintain his ‎failing marriage to Bella, he becomes disillusioned and depressed. ‎After the death of one of his closest colleagues, he recognises that he ‎needs a new challenge to avoid slipping into further despair. His ‎decision to move on would lead to many complex issues, and that, as ‎a logical thinker, it will test his mental agility, strength and resolve. ‎The working of his mind becomes something of a whirl as he ‎grapples with events alien to his upbringing.‎
