The Dempsey Sisters (2013) Deena, Sheena, and Tina Dempsey are sisters who have always shared everything growing up, including their love for singing! Fast forward to over a decade since their last performance, and the girls find themselves going through the motions, working average 9 to 5 jobs just to get by and make ends meet. The loss of her very posh and stable job ends up being the catalyst that catapults Deena into a place she never thought she'd find herself again; chasing her dream to sing. With the help of her older brother Thad who shows up on her doorstep with a parallel dream and a brand new wife, Deena plots to convince Sheena and Tina that it's not over until the Dempsey Sisters sing!
