On a lonely asteroid far from Earth, scientist Jay Hayling and technician Red Brewer are assigned to solve a baffling problem: the rock's mass keeps changing in ways that defy known physics. In their cramped, isolated outpost, the mystery begins as a technical nuisance—until the laboratory readings grow impossible and the ordinary becomes unsettling. What starts with jokes about low gravity and shaving less soon turns eerie when the pages of Red's book turn by themselves, as if an unseen presence is reading along. Jay's investigation leads him to a chilling conclusion: something invisible is sharing the asteroid with them, something alive, untouchable, and beyond ordinary instruments. As the mass continues to diminish, Red notices his clothes and shoes no longer fit, and Jay glimpses a beautiful woman in orange, suggesting the presence may be human—or something close to it. When Red is suddenly struck by an unseen hand, the haunting becomes undeniable, turning a scientific puzzle into a strange, otherworldly encounter.
