A Blanc-Biehn production explores the concept of a government-engineered drug intended to adjust or strategically modify perceptions formed during traumatic or stressful experiences. Promoted as a potential solution for problems ranging from racial conflicts and PTSD to geopolitical disputes, the drug requires a detailed study to understand its effects on individuals and determine appropriate dosages. Four couples are selected to participate in this trial, and they quickly find their memories and mental stability put to the test.
