Dystopian romcom bundles subcutaneous chips and color-changing tattoos into one plot device

Universal's "One Night Only" (dir. Will Gluck) opened August 7, 2026. Its premise: every legal-age adult gets implanted tracking chips paired with color-changing tattoos that enforce a "Sex Purge Law," limiting sex to one night per year. The film compresses real-world debates over biometric authentication, reproductive-health data trails, and body-level monitoring into a single on-screen mechanism.
