Oscar-nominated actor William H. Macy stars as Frank Gallagher, a single father of six who spends much of his free time drinking at bars. The Gallagher children -- led by oldest daughter Fiona (Emmy Rossum), who takes on much of the child-rearing responsibility due to her mother's absence -- manage to raise themselves in spite of Frank's lack of parenting and unusual parenting style when he does choose to act like a father. The drama is an adaptation of the BAFTA Award-winning British show of the same name.
