The Control Group

Jack wakes up in the abandoned institution with four other students and quickly takes a leadership role, trying to map the building and uncover the truth behind the experiment. He remains skeptical yet curious, using clues from the patient files to guide the group. His connection to the ghostly Anne provides crucial insight as they search for answers and a way out.

Heather is a resourceful and protective member of the group, contributing practical skills and courage under pressure. She forms bonds with the others as they navigate the hospital’s dangers. Her fate comes in a gruesome encounter, marking a turning point for the remaining survivors.

Grant is captured by plague-doctor-like figures and subjected to a transformation that leaves him zombie-like. He later reappears showing both his former self and the changed creature, and he resists Dr. Broward, adding to the upheaval. His uncertain fate underscores the peril of the experiment and the group's fight for survival.

Vanessa is part of the core group and faces mounting dangers as the hospital’s threats close in. She contributes to the group’s dynamics but ultimately falls victim to the looming perils, reinforcing the brutal stakes of their situation.

Anne appears as a ghostly presence who guides Jack and helps locate the 'Blank Slate' files. Her presence suggests a connected consciousness lingering beyond death, serving as a bridge between past patients and the current experiment.

Dr. Broward is the enigmatic and ruthless architect of the consciousness-storing experiment. He manipulates the system from behind the scenes, culminating in a confrontation with Jack. His downfall comes as the survivors ignite a rebellion within the facility, though his ultimate fate remains implied as they escape.
