Suddenly Seventeen

Suddenly Seventeen is a 2016 Chinese fantasy romance drama film starring Ni Ni, Wallace Huo and Darren Wang. It is the directorial debut of Zhang Mo, Zhang Yimou's daughter. It was released in China by Le Vision Pictures on December 9, 2016. Plot 28-year-old Liang Xia (Ni Ni) and 34-year-old Mao Liang (Wallace Huo) have been together for nearly 10 years and living together in Beijing for the past five. Liang Xia has given up a promising career as a talented painter to be a perfect, attentive girlfriend for her "Prince Charming," who she assumes will propose to her soon, but she is constantly disappointed as Mao prioritizes his work at a design agency over her. While morosely watching TV one morning, Liang sees an infomercial for "magic" chocolates that purport to grant youthful energy, and orders a box on a whim. Liang consults her best friend Bai Xiaoning, and the two of them concoct a plan publicly pressure Mao into proposing to Liang at Bai's wedding. However, the plan backfires, and Mao threatens to break up with her instead. The heartbroken Liang eats one of the chocolates and becomes disoriented while driving, rear-ending the car in front of her. When she regains consciousness several seconds later, her mind, memories, and personality have been replaced by those of her 17-year-old self, who is perplexed to find herself 11 years in the future. 17-year-old Liang ("Little Liang") goes out and parties with Bai (who marvels at Liang's transformation but is supportive), but her mind eventually reverts to 28-year-old Liang ("Big Liang").
