My Lucky Star is a prequel to ‘Sophie’s Revenge’. Su Fei works by day as a telephone booking clerk at a travel agency but also moonlights as a manga artist, sketching the romantic adventures of herself and a handsome secret agent. Her parents are always nagging her to find a husband instead of dreaming of the perfect man; meanwhile, her friends Li Li, Lu Xiaoxi and super-bitchy Xixi are more successful in the rich husband-hunting stakes. One day Su Fei wins a five-day trip to Singapore where, on the way to the hotel, she bumps into Chinese-American secret agent Yan Dawei, posing as David Chen, who, with his sidekick Bao, is on the trail of Gao, a ruthless gangster who is to take custody of a priceless diamond, The Lucky Star, that has been stolen from an exhibition in London and could be used for weapons purposes because of its high-grade industrial qualities. Dawei's mission is to stop the transaction, retrieve the diamond and find out whom Gao is working for. Su Fei immediately falls for Dawei, who looks exactly like the hero of her comic strips...
