Union Square chronicles the reluctant reunion of two estranged sisters: one on the verge of marriage, the other on the brink of a nervous breakdown.

A reluctant reunion of two estranged sisters. One is on the verge of marriage; the other is on the verge of a nervous breakdown. Both struggle with truths they're hiding from each other - and from themselves. Jenny has rejected her tumultuous family and cut off communication, seeking a more ordered life far from her roots in the Bronx. And she's almost ready to commit to her longtime fiancé when her sister Lucy - the personification of all that Jenny has been trying to flee - surprises her at a critical time. Lucy and Jenny's combustible reunion brings both of them to unforeseen places, shattering and reconstructing the worlds they have both carefully constructed.
