"One Night Only" embeds subcutaneous tracking chips and color-changing tattoos in a romcom premise

Universal's dystopian romcom "One Night Only," directed by Will Gluck, opened in theaters on August 7, 2026. Its premise: all legal-age adults received subcutaneous tracking chips with color-changing tattoos enforcing a "Sex Purge Law" that restricts sex to one night per year. The film collapses live debates about biometric authentication, reproductive-health data trails, and body-level monitoring into a single on-screen device.
