Paul Calleja is estranged from all but one of his family, his artist Great-uncle Lawrenz in far-off Malta. When he learns that his beloved Great-uncle has died, he flies immediately to pay his respects and to mourn the man who was more of a father to him than the one who had kicked him out for being gay. There, he discovers that Lawrenz had been protecting an incredible secret that centered on a collection of paintings featuring the mysterious and fascinating Angelo. Then there's the Caravaggio artwork that may or may not be a fake, which has been left to Paul in Lawrenz's will.

Angelo and Paul find an unexpected love forming between them, and Paul begins to dream of making a new life on Malta. Then Paul's brother turns up to claim a stake in what he thinks is the fortune left in Lawrenz's will, and another player steps into the game. Nico has an agenda of his own that endangers Paul's life and Angelo's immortal soul.
