London-based investigative journalist Robert Torres visits Spain to research a book about Josemaría Escrivá, the controversial founder of Opus Dei. But Robert hits a wall, both professionally and personally, when his most promising source -- his own father, Manolo Torres, turns out to be his least cooperative one. Robert begins to unearth his father's toxic secrets when he learns that Manolo was not only born in the same Spanish town as Josemaría, but that they were childhood friends and attended the same seminary. The two men take radically different paths in life, with Josemaría dedicating his life to his faith while Manolo is swept into the brutal and tumultuous Spanish Civil War.
