Lucy Ramos is out for blood-she needs to kill a man, but she has no clue how. Lucy calls on the help of aged hit-man, Tito Garza-also known as El Perro of Pedro. Garza's signature method of killing? Using dogs to maul his targets to death. Now, in his golden years, Garza lives a mundane life in San Pedro, a port town south of downtown Los Angeles. With a backpack full of cash, Lucy persuades Garza to help her murder her mother's killer, Assistant District Attorney Victor Soto. Together, the forgotten hit-man hungry for a comeback and the girl whose life was shattered as a child set out to kill the man responsible. But killing Victor Soto may prove to be an impossible task. The newly elected Assistant District Attorney's wealth and political clout keep him well-insulated. Lucy and Garza's plan is further complicated when Lucy begins to develop feelings for Victor Soto's son, Martin. With their romance threatening to derail the mission, Lucy fights to keep Martin out of Garza's cross-hairs when his violent urges become more unpredictable. Will Lucy's feelings for Martin jeopardize everything she's worked for? Will Garza's unchecked rage cause innocent people to die? Lucy Ramos and Tito Garza are furious, deadly, and driven by vengeance-but vengeance comes at a price.
