A straightforward metaphor underlies this film, which shifts between being irritating and visually appealing. It suggests that romantic feelings and intense desire are comparable to a nuclear reaction—something potentially destructive, like an illness stemming from a powerful energy source. Regrettably, while this sickness generates considerable anxiety and discomfort, it doesn’t really spark much creativity… The narrative centers on Gary (played by Tahar Rahim, who previously starred in A Prophet, 2009) as he searches for employment at a nuclear facility in the Rhone valley, and can be interpreted as a story about exploitation. The film depicts him being exposed to progressively higher levels of radioactive contamination alongside frequent outdoor sexual encounters with Karole (Seydoux), who is engaged. This combination of erotic drama and environmental thriller is certainly distinctive due to its central themes. However, the narrative loses momentum because the core plot developments and character portrayals don’t advance beyond the sex scenes, the fear of being caught, and a vague sense of potential racial discrimination. Beyond the film itself, the soundtrack composed by French musician Rob deserves attention; it's quite good. As an additional positive aspect, it complements the imagery of the lush valleys and fields remarkably well. The cinematography is excellent, showcasing the French countryside in stunning detail as the two lovers meet for their regular rendezvous near the nuclear plant. However, this beautiful depiction cannot mask the fact that the film overall feels somewhat muddled and uninspired. By its conclusion, viewers might find themselves questioning what the intended point was.
