Jonathan Laing; rootless and lonely, he is horrified when he wakes up bandaged in a burns unit with no memory of how he got there.

Blake Roth; violent criminal, finds himself behaving increasingly erratically after an attempted mugging backfires on him.

As each man contends with a terrifying and baffling new reality, they slowly come to realise that they have become inextricably tangled.

But there are so many questions. Like; what happened that night, and what is happening to them now? Why can't they seem to shift their thirst? And when will this unseasonal heatwave break?

As one searches desperately for answers, the other tries to flee them. But the truth is hunting both men and they must both decide how they will choose to face it.

And how they will deal with that ferocious, unquenchable thirst.
