Every month, when the welfare money runs out, 35 year-old Catherine (Anastasia Phillips) has to talk her self-destructive mother off the ledge of the same bridge...literally. This routine has gone on for so long that it's the only thing Cathy feels she's good at. And its Tammy's selfish way of keeping hold of her daughter. When Tammy (Felicity Huffman) is diagnosed with terminal cancer and the possibility of life without her becomes very real, so does Cathy's repressed desire to leave her small town. Does she stay and trust the woman who has always let her down, or does she find the courage to live her own life?
