For the past forty years, Ah Long has headed up a traditional Chinese musical troupe. His oldest son, Ah Hui, is an aimless slacker with no plans for the future. His younger son, Ah Ming, is musically talented but physically handicapped and so has developed an eccentric and closed personality, raising pigeons as a way to escape social interaction. One day, Ah Hui and Ah Gou find out that the two doors of their local temple, with door gods painted, are in fact antiques of great value. They steal the doors and sell them to a dealer in stolen artifacts. Excited with the payment they receive, they start looking for other opportunities to steal more goods. However, the next time Ah Gou visits the dealer, he discovers him lying on the floor. Just as Gou is picking up the gun that he has found next to the body, the police arrive. In a panic, he takes the gun with him and runs away. Ah Long has won round-trip tickets to New York City. He and his wife, along with a few other friends, travel in small tour group to Manhattan. When they are all having a meal in a restaurant, they discover the stolen doors being used as decoration. They negotiate with the owner and successfully buy the doors back. Meanwhile, Ah Gou and Ah Hui are desperately fleeing, finally hiding in Ah Ming's pigeon coop. Ultimately, to the sound of Ah long and the other tour group members' cheerful singing under the bright lights of New York City, there is a final shootout between the police, Ah Gou, and Ah Hui on the rooftop in Taipei.
