Over the next few months, Kit trains the cousins in her business and marksmanship. Mark and Michael develop an attraction to her and Kit is attracted to Mark. Despite his feelings, Mark does not reciprocate Kit's affections to avoid hurting Michael, who thinks Kit is in love with him. Kit manages to secure safe passage for Mark, Michael, and Michael's father back to Hong Kong. The three return and start a new business there. The leader of the arms smuggling company (and Kit's former lover), Sam Ho Cheung-ching, returns after a three-year absence when he was presumed dead. Jealous of Kit's relationship with Mark and Michael, he plots to kill the cousins. Ho sends a bomb to the business, which kills Michael's father. Ho and his men capture and beat Mark and Mun, warning them to stay away from Kit. Kit expresses her regret for Michael's father's death and to share her feelings with Mark, which he reciprocates. Ho returns to Vietnam, taking Kit with him, to complete the deal with the Vietnamese warlord encountered earlier in the film. Mark and Michael follow Ho back to Saigon, intending to kill him. Mark steps off the plane attired in his iconic outfit as seen in the first "A Better Tomorrow": black duster, sunglasses, and matchstick in his mouth. At an abandoned temple, where Kit meets Michael to give him two plane tickets to leave Saigon with Mark they are unexpectedly surrounded by Việt Cộng troops. They engage in a shootout with them. While trying to escape from them in a jeep driven by Pat, due to the bumpy ride, Michael falls off the jeep and gets caught in an explosion. Mark confronts Kit in her hotel concerning Michael's assumed death accusing her of betrayal and keeping secrets from him. Then enraged by her answers to his accusations he slaps her a few times. Before he leaves her room, he tells her he wants nothing to do with her. Ho and Kit head to their deal with the Vietnamese warlord. The warlord attempts to double-cross Ho. A shootout ensues. Mark came in the room dual wielding two M-16 rifles, intending to take his revenge on Ho after the shootout between the warlord and Ho died down. During the shootout between Ho and Mark, Kit is severely wounded by one of Ho's men and Ho is killed by the warlord. Michael, who survived the explosion, arrives with Pat to help Mark make his getaway with the wounded Kit.
