Cal Jackson has just been released from prison. Now all he wants is a quiet life.

But when his sister marries into the family of corrupt businessman Francis McArthur, Cal finds himself caught in the middle of an ongoing war between his new family and the police.

When a childhood friend, the mysterious and enchanting Elise Moreau, disappears, Cal's got his work cut out to find her and discover what links her to McArthur.

And that's before the first dead body turns up.

As a heat wave grips Glasgow's mean streets and vibrant night life, Cal is reluctantly forced to act, before he finds himself either back in prison, or buried in the ground.
