Rob and Sally need to uncover an ancient secret. But he's losing control—and loving it.

Robert Stevens has known Sally Langtry for almost his whole life. They've been friends forever, and he's always secretly loved her. Sally, an artist, is so sweet he can't possibly be the right man for her. She's free-spirited, innocent and optimistic. Rob has always resisted bringing the darkness of his job, the horridness of what he sees day in and day out, into her life.

He is urged by his colleague, El, and his boss to turn to Sally for help in looking for a stolen Cezanne masterpiece. At a loose end and unsure where else to turn, he does so. El and her lover James recover the painting, but Sally's curiosity is now piqued. She wants to tag along to study the work of art. Rob, always helpless when it comes to indulging her, agrees. Sally helps discover a series of codes hidden within the picture.

Deeply curious now, both Sally and Rob visit the artist whose work Sal recognises.

The action becomes deadly, but it's too late for them to turn back. Rob tries to protect Sally, but he no longer has the legendary control he's so used to working with.
