Miss Granny () is a 2014 South Korean comedy-drama film directed by Hwang Dong-hyuk. Na Moon-hee stars as a woman in her 70s who magically finds herself in the body of her 20-year-old self (Shim Eun-kyung) after having her picture taken at a mysterious photo studio. After opening in theaters on January 22, 2014, it became a huge box office hit, with 8.65 million tickets sold.

Plot

Oh Mal-soon, a 74-year-old widow, lives with her son and his family. Foul-mouthed, stubborn, controlling and shameless, she has a difficult relationship with her depressed daughter-in-law Ae-ja, but is very proud of her son Hyun-chul, who became a university professor of gerontology, and whom she raised by herself against all odds. One day, Ae-ja gets hospitalized after suddenly collapsing. Her doctors strongly advise her to live apart from Mal-soon. On the day she is told by her son that she is being sent to a nursing home, the dismayed Mal-soon wanders the streets and comes across a mysterious photo studio that claims it captures the moments of one's youth. She takes what she believes will be her last self-portrait for her not-so-far-off funeral, but when she comes out of the studio, Mal-soon is dumbfounded by her own reflection in the mirror: she's now a fresh, young 20-year-old woman.

Miss Granny

At first not knowing what to do, she hides from her family and soon ends up lodging with her fellow café shop worker who used to be a servant of her family. With no one recognizing her, Mal-soon decides to make the most out of this once-in-a-lifetime opportunity. She renames herself Oh Doo-ri after her all-time favorite actress Audrey Hepburn, gets a haircut similar to Hepburn's in Roman Holiday, and takes advantage of her youth. As the "suspicious girl" of the Korean title, all anyone sees is that Doo-ri speaks with a regional accent and walks like an old lady, and that she acts very strangely and motherly for her age. After wowing a group of pensioners with a stirring karaoke tune one day, she attracts the notice of her unknowing grandson Ji-ha, a 4th year in university, and Han Seung-woo, a TV music producer. Ji-ha invites her to join his heavy metal band, and after she convinces them to switch to more audience-pleasing melodies.

Miss Granny

She gets caught romantically between two men: Mr. Park, her now ex-café worker friend who had always secretly loved Mal-soon, and Seung-woo, who's doing his best to track her down again. Mr. Park's daughter forces her out as she thinks Doo-ri is scheming after his money and she takes refuge in Mr. Han's apartment.

Miss Granny

Meanwhile, the band becomes successful with her as vocalist and Seung-woo decides to take them under his wing. Doo-ri is thrilled to be pursuing a career in music ― something she had to give up when she was young. They are booked for an extravaganza at the studio and Ji-ha is late due to a traffic jam. He decides to leave the taxi and bike but is hit by a lorry on the way there. He is in a critical condition at the hospital but Doo-ri decides to go on stage so as to tell him that his song was a success afterwards. As she arrives at the hospital it is found that only she has the correct blood type for a transfusion. She does the transfusion knowing that it would return her back to her aged condition.

Ji-ha's band takes off with the sister as the lead singer and Doo-ri as a fan. Mr. Park finds the same photo studio and becomes young and handsome. He picks her up at a bus stop and rides off bickering good naturedly as they always do.
