Instead of going to New York to create a better future for himself and his mother, the poor stowaway, Kostas, finds himself indebted to the ocean liner's compassionate doctor, Petros. In return for the favour, Kostas has to meet Petros' beautiful but unknown pen-pal, Rena, with whom he has been exchanging fervent love letters under the nose of his jealous fiancée, Julia. Of course, it's love at first sight for Kostas and Rena; however, things are bound to take a turn for the unexpected, when a furious Julia unearths one of Rena's billets-doux. Will Rena ever forgive her good-hearted liar?
