Legendary Witches(전설의 마녀)

Orphan Moon Soo-in marries Ma Do-hyun, the eldest son of the chaebol family who owns bakery corporation Shinhwa Group. But when Do-hyun dies unexpectedly, the Ma family makes Soo-in take the fall for their illegal business practices and she ends up in jail for stock manipulation that she didn't commit. At Cheongju's Penitentiary for Women, her cellmates are kind-hearted Shim Bok-nyeo who was falsely accused of killing her husband and son; tough-as-nails, foul-mouthed Son Poong-geum who was convicted of fraud; and former model Seo Mi-oh who's been charged with the attempted murder of her boyfriend, Shinhwa Group's youngest son. The four women bond and become friends, particularly when they join the baking classes being taught by Nam Woo-suk, a hotel chef. Woo-suk is a widower who is raising his daughter alone after the death of his wife six years ago. At his father-in-law's suggestion, he became a volunteer at the local prison's vocational training center, where he meets Soo-in and begins to fall for her. Upon their discharge, the four women put the baking skills they learned in prison to use, opening up a bakery together. But they face stiff competition from the Shinhwa Group.
