Tower (Nadech Kugimiya) is a suave con-artist who gives himself away accidentally while trying to con Ina (Pimchanok Luevisadpaibul), a goofy banker, out of some money. After Ina catches Tower red-handed, she proposes a deal: she won't turn him in to the police if he agrees to use his skills to con Petch (Thiti Mahayotaruk), Ina's ex-boyfriend who tricked her into borrowing money to pay his tuition, then left her hanging in the wind owing 100,000s in debt. The mission takes on a whole new level when Tower changes the plan from conning 100,000s to millions. This con job will take a team made up of Ms Nongnuch (Kathaleeya McIntosh), Ina's high-school teacher, who pretends to be a foxy businesswoman; and Mr Jone (Pongsatorn Jongwilas), Tower's brother, a thief who has a long history with the law. But even before the plan starts, Ina has a change of heart about Tower. Will she be fooled twice? Is she fated to keep meeting gorgeous con-artists? The con job must go on, but can Ina keep her heart from falling for another bad guy? Find out in THE CON-HEARTIST, a romantic comedy by the director of I FINE..THANK YOU...LOVE YOU.
