A personal take on the Medea Myth: 

Cathy is a mother who has shoved her children out of her house with a tendency to hoard. However, when she's diagnosed with Huntington's disease she understands it's time to change--and time to move, but she can't do it without her estranged sons help. When the boys return, they have to come to terms with their mother's hereditary disease, and their own death sentence.
