A tale that
follows 'the Guy', who works part-time helping his father run a small,
vacuum cleaner repair business, but dreams of one day having his songs
recorded and landing a record deal. Emotionally vulnerable, he is still
coming to terms with the recent departure of his girlfriend and lacks
the conviction and passion to move on in his pedestrian life. One day,
he meets 'the Girl', an Eastern European immigrant who has moved to
Dublin to start a new life for herself. Currently working as a house
cleaner in an upper-class residence, she is struggling financially. She
yearns for what she cannot afford--a piano to help her escape from the
daily grind of finding her way through this strange new land. A
relationship blossoms between 'the Guy' and 'the Girl', as they're both
struggling. Their shared love of music causes them to flourish and grow
with a new found confidence as they take a chance on each other and a
new beginning on life.
