Marvin Gable is a successful real estate agent who has recently been awarded the highest honor by his boss, friend, and mentor Cliff Cussick. He is often accompanied by his cynically depressed assistant Ashley, who constantly threatens leaving her job, despite Marvin's pep talks. In actuality, Marvin is a former assassin for "The Company", run by his estranged brother Alvin, AKA "Knuckles". He was to eliminate a young lawyer, Rose, after she stole from the company, but due to his love for her, he told her to run instead before choosing to leave his old life behind. In the present, around
Valentine's Day, Marvin receives a letter from Rose. He is later confronted by knife assassin and poetry obsessed Raven, who has been hired to find the whereabouts of Rose. Marvin knocks Raven out and leaves him in his office. He heads back home to collect his things before two more agents, King and Otis, confront him. Marvin manages to defeat the two before he is captured by Rose, who takes him back to her hideout at a strip club. Meanwhile, Ashley discovers Raven as well as his poetry and falls in love with him, where he in turn admires her appreciation for his work. Cliff goes to Marvin's house where he is confronted by Knuckles, who tells him of Marvin's former life. Despite this, Cliff respects Marvin's efforts to change and Knuckles kills him when he declares that they are "brothers". Rose tells Marvin she has collected an insurmountable degree of information of Knuckles' frequent money laundering, revealing that he has been cheating several partners, and has even captured his accountant, Kippy Betts. She had also been coercing Knuckles' right-hand man Renny Merlo, who was going to double cross her for fear of Knuckles finding out that he had stolen from him. Rose plans to use Kippy's information to finally take down Knuckles, and wants Marvin to return to his old ways to help her out. Having hid in one of the houses Marvin is selling, a couple that Marvin previously spoke to arrive, forcing him to finalize his work with them. He contacts Ashley and asks that she bring the papers, unaware that Raven is with her. Kippy manages to escape and contacts Renny, who in turn orders King and Otis to come as well. As Rose leaves to confront Knuckles, Raven, Ashley, Otis, and King arrive and a fight breaks out, resulting in the death of Marvin's overzealous rival Jeff Zaks. Marvin and Raven team up and take out Otis and King, but Ashley insists that Marvin and Raven cease their fight as she is in love with the latter. Inspired by this, Marvin pursues Rose to Knuckles' hideout and they fight through his men, with Merlo getting killed. After realizing his brother murdered Cliff, Marvin has one final fight with Knuckles, ending with him victorious. Rose reveals that she contacted the Russian gangsters that Knuckles had cheated, resulting in them coming and taking him away. Marvin finally declares his love for Rose, proudly embracing his past and future. ==Cast==
