With her gravely-ill piano instructor grandfather on his deathbed and after three months of costly medical care, Mariana's poor family is in a very tight spot. Unable to pay for medicine--let alone pay off a hateful debt of fifteen thousand drachmas--Mariana and her mother, who is utterly unprotected before the relentless court enforcement officer and his helpers, can only pray for a miracle to save them. And just like that, Nikos--Mariana's compassionate fiancé--repays their financial obligation in full; however, the money is not his. How will the honest but penniless man settle his heavy debt? Moreover, who is that mysterious stranger who claims to know Mariana's grandfather?
