And not knowing what to expect, vivid flashbacks of his eventful childhood in 1960s Greece pave the way for a sentimental trip down memory lane. Surprisingly, Stefanos still has the sweet taste of love's first kiss in his mouth. But so does Marina. Because back then, an innocent kiss marked the beginning of an impossible relationship. Decades later, the same peck on the lips is about to reunite two estranged soulmates. However, are they still having feelings for each other?
