Meet The Gallaghers! Dad is an addict, Mom is M.I.A. so it's up to Fiona, the oldest, to take care of her 5 brothers and sisters in one of Chicagos' roughest neighborhoods. With her oldest brother Philip (Lip) entering rehab, her gay brother fighting to keep his EMT job because of his bipolar disorder, her 15 year old sister Debbie and HER new baby, Carl (there aren't enough words), her youngest brother still in preschool, and her almost marriage, Fiona has her work cut out for her in keeping this family from losing everything, including each other.
