Interaction.

Rebecca cleans houses to make ends meet, but her true passion is recording her clients without their knowledge. Eavesdropping on their private moments, she compiles a library of fights, family meetings, confessions and hookups - an array of emotions to taste-test, rewind and revisit as she likes. When she encounters Martin, a self-secluded man who harbors violent fantasies, Rebecca creeps down from her voyeuristic listening post. Helpless to resist, she engages with him in a visceral but contactless transaction - as grave as life and death but just within earshot.
