Fans of Cube and Stuart Hazeldine's Exam cannot miss this high-stakes sci-fi thriller movie that demonstrates how vast, universe-ending concepts can be constructed inside four bare walls.
The plot unfolds rapidly within the confines of a single, locked chamber, where four academics in various mathematical and physical disciplines—Sandra, Carol, David, and Kate—are mysteriously assembled. Upon arrival, they are informed via a pre-recorded message from the enigmatic Dr. Wahlstein that he has perished, leaving them locked in the room with an electrified door and a cryptic sequence of numbers. As the intellectuals decipher the mathematical sequence, they realize they are dealing with conformal cyclic cosmology and the catastrophic collapse of the multiverse. Forced to bridge their professional rivalries, the group must solve the cosmic puzzle before time itself folds in on them.
Positioned firmly alongside claustrophobic, cerebral "bottle-episode" thrillers like Vincenzo Natali’s Cube and Shane Carruth’s Primer, director Bjorn Engström’s work relies entirely on the weight of high-concept physics rather than visceral spectacle. Operating within the 2010s wave of low-budget, idea-driven science fiction, the film eschews sprawling special effects in favor of intense, intellectual paranoia. Critical consensus highlights the performances of Jennifer Lila as Carol and Vee Vimolmal as the prickly, pragmatically minded Kate, both of whom ground the dizzying theoretical dialogue with a starkly human tension.
The mathematical equations and cosmological formulas endlessly scribbled across the room's blackboards were drawn directly from actual theoretical research on cyclic universes, serving as real-world Easter eggs for viewers versed in higher physics.
