Every Contact Leaves a Trace

Since 1990, filmmaker Lynne Sachs has collected 600 business cards—from a hairdresser, a therapist, a textile artist. Together they form an archive of encounters. The title of this imaginative essay film, Every Contact Leaves a Trace, is a basic principle of forensic science, coined by Edward Locard, a pioneer in the field. And any trace can link a person to a place, another person or an object. If that’s true, Sachs wonders, might every personal encounter not also leave a trace on your being?
