A group of scientists is summoned to investigate a mysterious extraterrestrial object discovered at the bottom of the ocean. The mission, led by the enigmatic Dr. Norman Goodman, brings together a psychologist, a marine biology expert, and a mathematician, each with a complicated past. As they descend into the depths of the sea in an impressive yet claustrophobic research station, they discover a glowing sphere, which turns out to be an artifact of unknown origin.
At first, the sphere appears harmless, but soon it becomes a source of unease as team members begin to experience visions and manifestations of their own repressed fears and desires. As the atmosphere becomes tense and relationships between them deteriorate, the boundary between reality and paranoia blurs. They must not only grapple with the horrors that emerge from their own psyches, but also uncover the mystery of the sphere before its influence consumes them completely.
With a psychological focus and a suspenseful atmosphere, the film delves into the complexity of the human mind and the traumas of the past, prompting the audience to question what is real and what is not. As the dark secret of the sphere unfolds, the team faces the reality that not everyone may survive this journey into the abyss of their own emotions.
