Sisyphus

Greta and Marlene are two close friends who are both going through tough marriages. They share a long and secret history together and when one of them decides to make the next move in their relationship by pursuing a wonderful moment in their lives, she is met with resistance. As time goes by their roles revise and they try to get back on track but like Sisyphus, they might be rolling a boulder up a hill just to watch it roll back down again.
