Title: Four Brothers Movie plot: On a cold, snowy night in Detroit, an El Camino car follows another around town. The car that the Camino is following parks and the driver gets out and walks into a convenience store. The driver is Evelyn Mercer (Fionnula Flanagan), a good-natured, elderly woman. She catches a young boy named Darnell (Tahliel Hawthorne) stealing a candy bar and reprimands him before telling the cashier, Samir (Pablo Silveira), to call the police. We see that Evelyn is bluffing but she uses her threat to talk sense in Darnell who promises to never steal again before he leaves the store. Evelyn admits to Samir that Darnell just needs an older brother as she walks to the rear of the store to pick out a Thanksgiving turkey. The El Camino occupants (Richard Chevolleau and Awaovieyi Agie) get out of the car and enter the store, clad in black hoods and wielding shotguns. They demand money from Samir as Evelyn hides behind a counter. She listens as Samir hands over the money before they shoot him dead and gasps, a sound that the hoodlums hear. Outside the store, a second gunshot is heard before the robbers leave the store and take off.Bobby Mercer (Mark Wahlberg) drives back into Detroit after an absence to attend his adopted mother, Evelyn's, funeral. He greets his brothers Jeremiah (Andre Benjamin) and Jack (Garrett Hedlund) who gives an emotional eulogy on how Evelyn taught him that he didn't have to be afraid anymore and what it meant to be part of a family. Everyone goes to Jeremiah's house later for reception where Lt. Green (Terrence Howard) briefs his partner, Fowler (Josh Charles), on the Mercer brothers before joining. All wards of the state, the four brothers, currently minus Angel ([linknm0879085]), were raised and adopted by Evelyn herself after she failed to find them appropriate homes elsewhere. Bobby, the oldest brother, holds a reputation as a heavy weight, getting kicked out of hockey after multiple offenses. Jack is the youngest and a "first class fuck-up, third class rock star". Jeremiah is the only brother to...???

Question: Who does Hitman Joe hire as his go-between in Bangkok? Title: Bangkok Dangerous Movie plot: Joe (Cage) is a professional freelance contract killer. He works strictly by the rules; He never socializes outside his work, he stays secluded in quiet spots, never meets his handlers and always leaves on time, leaving without a trace. He usually hires young pickpockets or small-time criminals as his local help, whom he usually murders after the end of the job to prevent any identification. He uses multiple aliases and also has middlemen between him and his handlers. He also carries a watch to perform a hit in specific time and correctly visualizes his every target. After completing a hit in Prague and killing his current help, Joe travels to Bangkok for an assignment to assassinate four people for notorious Bangkok crime boss Surat, whom he never meets. Joe occasionally provides insight via voiceover narration throughout the film. He hires a local pickpocket with simple English knowledge, Kong, as his go-between in Bangkok, a condition of the contract being that the gang will never meet Joe. Contracts from the Bangkok gangsters are passed to Kong one by one via a nightclub dancer, Aom. Joe's first execution in Bangkok is done on motorcycle; when the target car stops at a red light, Joe kills all the passengers with a machine pistol. Kong retrieves information about the second target, again via Aom, and the pair become friendlier with every contact. Before Joe executes his mission, Kong informs him of the target, Pramod Juntasa, another notorious gang lord and Surat's rival crime boss who acts as sex trafficker, buying young girls from impoverished parents and selling them after sex deals. Joe sneaks into the target's penthouse and drowns him in his pool. Unsatisfied with Kong's assistance, Joe contemplates killing him, but after a brief confrontation when Kong is ambushed by local gangsters regarding a briefcase containing information files of Surat's/Joe's targets, he instead decides to act as Kong's mentor and trains him for self-defense. Midway through the movie, Joe meets Fon, a deaf-mute pharmacist,...
