Beautiful blossoms flourish in the front of the Florería Roma-- but dangerous plans are blooming in the back room. Harry, an un-employed American newspaper reporter, comes to Mexico to have a good time. He wants to see the sights, play golf, go fishing, and hit the beach. His first night in Mexico City he has dinner with Rosa, a blue-eyed blonde Mexican girl, and he stumbles on a body in the back of the restaurant. From then on, he and Rosa are forced to fight for their lives, caught in the middle of a complex Cold War conspiracy to sabotage and eventually to take over Pemex, the government oil monopoly. Within days of arriving Harry has three job offers, including an offer from Rosa’s boss at the Florería Roma, and another for a part time job with United Press. When he visits the back room of the flower shop he discovers that the conspiracy goes well beyond the Pemex takeover and includes assassination and catastrophic global disorder.
