Pink Lips are a sign of grace and beauty, but for sisters Willow and Kail, they mean power. The women pay a massive fee to join an organisation and get their lips etched in pink, and life is good until an accidental phone call dismantles the whole organisation. Their lives upended, they flee to Philadelphia. With a hunger for money, they try to resurrect the organisation. But when Willow meets neighbourhood hardhead Duke, she falls in love. Kail objects, and the sisters turn against each other. Skeletons come out of the closet as both ask if blood is really thicker than water.
