Jack Burton is driving his semi-trailer truck, nicknamed the Pork Chop Express, while narrating a monologue over the Citizens band radio (CB). He arrives at an outdoor market, drinking and gambling throughout the night. In the morning, Jack wins a bet with Wang Chi in a game of reflexes. To make sure he follows through on payment, Jack accompanies Wang to meet his fiancée Miao Yin at the airport, where they are confronted by Lords of Death gang members, who capture Miao Yin for her green eyes.
Jack and Wang track the gang to Chinatown, where they encounter a funeral procession which erupts into battle between the Chang Sing and Wing Kong, two ancient Chinese warrior societies. Three supernatural warriors with weather-themed powers appear: Thunder, Rain and Lightning (known as the Three Storms). Jack attempts to drive away, but seems to run over Lo Pan, a magician standing behind the Storms. However, Lo Pan is somehow unhurt. Wang and Jack escape through the alleys, but Jack's truck is stolen.
Wang takes Jack to his restaurant, where they meet Wang's friend Eddie Lee, Gracie Law and her journalist friend Margo. The group devises a plan to infiltrate a brothel, where they believe Miao Yin is held captive. They break in, but are interrupted by the Storms, who capture Miao Yin and bring her to Lo Pan.
Jack and Wang track down the front business used by Lo Pan and impersonate telephone repairmen to gain access, but are quickly subdued by Rain. After being tied up and beaten, they meet Lo Pan. He now appears as David Lo Pan, an elderly and feeble businessman. Jack and Wang's friends attempt to save them and are also captured.
Locked in a cell, Wang tells Jack that Lo Pan needs a green-eyed girl to break an ancient curse, and he intends to sacrifice Miao Yin. Centuries ago, Lo Pan was defeated in battle by Emperor Qin Shi Huang, who cursed Lo Pan with incorporeality. Lo Pan can temporarily obtain a decrepit body by supplication to the gods, but he must marry and sacrifice Miao Yin to fully lift his curse. They eventually escape, and free Gracie, Margo and a group of women kept in cells, but a Wild-Man creature grabs Gracie before she escapes. Lo Pan notes that Gracie also has green eyes and decides to sacrifice her while making Miao Yin his wife. Wang and Jack regroup with the Chang Sing warriors and Egg Shen, a powerful magician, and enter a cavern to return to Lo Pan's headquarters. Before the final battle, Egg Shen pours the group a potent potion, which boosts their confidence for the upcoming battle.
They interrupt the wedding at Lo Pan's lair and begin fighting. Jack accidentally knocks himself out, while Wang engages Rain in a sword duel. Lo Pan draws some of Miao Yin's blood and consumes it, regaining his corporeal form. Jack eventually regains consciousness and joins the fight. Lo Pan recognizes Egg Shen and they engage in a magic duel. Lo Pan and Thunder escape the lair with Miao Yin as the fighting continues. Wang is able to kill Rain, while Jack rescues Gracie. They regroup and confront Lo Pan further into his headquarters. Wang fights Thunder hand-to-hand, while Jack and Gracie rescue Miao Yin. Jack throws his knife at Lo Pan and misses, but when Lo Pan throws the knife back at Jack, he catches it and instantly throws it into Lo Pan's forehead, killing him.
Upon finding Lo Pan dead, Thunder swells up with rage and explodes. Jack, Wang, Gracie, and Miao Yin are cornered in a corridor by Lightning, who triggers a collapse of the lair. They are rescued by Egg, who drops a stone statue on Lightning, killing him. The group escape back to Wang's restaurant in Jack's truck, where they celebrate. With his old enemy defeated, Egg takes a long overdue vacation. Wang and Miao Yin prepare to marry, while Eddie pairs with Margo. Gracie offers to join Jack, but he declines, saying he eventually rubs everyone the wrong way. In the final scene, unbeknown to Jack as he is driving alone while speaking on the CB radio, it is revealed that the Wild-Man has survived the battle and has stowed away on his truck.
Big Trouble in Little China originated from a script by first-time screenwriters Gary Goldman and David Z. Weinstein. Goldman had been inspired by a new wave of martial arts films that had "all sorts of weird actions and special effects, shot against this background of Oriental mysticism and modern sensibilities", such as The Butterfly Murders; Weinstein, for his part, was fascinated by the historical Tong Wars of 19th-century San Francisco's Chinatown. The duo combined these interests with a shared fondness for classic westerns to write the first iteration of the screenplay.
Reception
Opening in 1,053 theaters on July 2, 1986, Big Trouble in Little China grossed $2.7 million in its opening weekend and went on to gross $11.1 million in North America, well below its estimated budget of $19–25 million, making it a box-office bomb. The film was released in the midst of the hype for James Cameron's blockbuster Aliens, which was released 16 days after. On the DVD commentary for Big Trouble in Little China, Carpenter and Russell discuss this among possible reasons for the film's disappointing box office gross.
