Parts Per Billion (2014): Cast & Plot

Anna, Teresa Palmer, and Erik, Penn Badgley, are a wealthy, music-loving couple whose days are cushioned by Erik’s family fortune. Erik is a struggling musician more focused on his craft and keeping amicable ties with his exes than on the couple’s day-to-day life, while Anna grows increasingly anxious about the fragility of their seemingly comfortable existence. They clash over seemingly trivial details, yet the undercurrent of unease grows as Anna watches headlines about escalating conflicts in the Middle East. She begins to believe they should spend more time together, to anchor themselves against a world that feels increasingly volatile. But Erik drifts toward his composition and his social circles, and the distance between them widens, masking deeper fears with casual routines and shared, but shallow, routines.
