Swindler in My Mom's House", left, is a comic remake of a 1961 classic "Mother and the Guest in the Room of Master ", right, that traces the unspoken love between a gentleman lodger and a widow, played by actress Choi Eun-hee. But in the modern version, a pigtail-wearing mother and precocious teenage daughter both try to win the heart of a conniving Casanova staying at their house.
Hae Joo (Kim Won Hee) is a simple-minded, young mother who makes a living by renting out a room to passing travelers and selling flowers. Her undeniable beauty makes her the object of desire amongst the many bachelors in their small rural village. But the lonely widow has her heart set on her new visitor from Seoul, tall and good-looking veterinarian Duk Geun (Jung Jun Ho). Never the shy type, Hae Joo literally throws herself on him, much to dismay of her daughter and longtime admirer Sung Chil. For Duk Geun, a swindler in pursuit of money, Hae Joo's overtness is a nuisance - until he discovers her one million-dollar bank account. All of a sudden, there is a swift turn in the tide and Duk Geun is the one trying to win Hae Joo's heart using all of his known techniques. But, watch out, this naive-looking widow is not to be underestimated.
