The Invisible Man (2020)

⁣Trapped in a violent, controlling relationship with wealthy optics engineer and businessman Adrian Griffin, Cecilia Kass drugs him with Diazepam and escapes their home into the nearby woods to wait for her sister Emily. After she arrives, Adrian nearly catches Cecilia, but the pair are able to escape.
Cecilia hides out with childhood friend and Emily's ex-husband James and their teenage daughter Sydney. Two weeks later, Adrian seemingly commits suicide and leaves Cecilia $5 million in his will, handled and organized by his lawyer brother, Tom. As Cecilia tries to move forward, she is plagued by several unexplained experiences. During a job interview, she faints after finding the contents of her portfolio removed and is taken to the hospital. Later, the doctor calls and says they found high levels of Diazepam in her system. Shortly after returning home, Cecilia finds the same bottle she drugged Adrian with, which she dropped during her escape, in her bathroom.
She arranges a meeting with Tom and James, insisting that Adrian faked his death and used his optics expertise to become invisible in order to torment her, but gets rebuffed. Cecilia turns to her sister, but Emily refuses to acknowledge her after receiving an email from Cecilia's account stating she never wants to see her again. Later, she is comforted by Sydney, but Sydney is hit by an unseen force, leading her and James to assume Cecilia did it. While a furious James rushes his daughter out of the house, Cecilia tries a number of tactics to catch the figure. After finding Adrian's old phone in the attic and covering the figure with paint, she ends up in a violent struggle and escapes to Adrian's home to investigate. In his lab, she finds a suit that confirms her suspicions. After hiding it in a closet, the invisible figure attacks again, so Cecilia flees and contacts Emily. The pair meet in a restaurant, though as Cecilia begins to tell her what she found, the invisible figure slits Emily's throat with a knife and places it in Cecilia's hand; framing her for the crime.
Remanded to a mental hospital while she awaits trial, the staff informs Cecilia that she is pregnant. Tom visits her and offers to get her charges dropped if she agrees to "return to him" and raise the child, implying that he helped his brother stage his suicide while revealing Adrian tampered with her birth control to ensure she became pregnant. Cecilia refuses to take the deal and steals a pen from his briefcase. That night, she uses the pen to pretend to commit suicide to draw the invisible figure out. When the figure tries to stop her, she stabs him repeatedly, causing the suit to malfunction. The security team arrive, but the invisible figure violently incapacitates them before fleeing the hospital, with Cecilia in pursuit. Promising not to harm her because of her pregnancy, the figure instead threatens to attack those she loves.
Cecilia races to James' house, where she finds the invisible figure attacking him and Sydney. She manages to shoot the figure after spraying him with a fire extinguisher, but when she unmasks them, she finds Tom in the suit. Police find a captive Adrian alive at his house, tied up in his basement and claiming Tom held him prisoner. Cecilia quickly disagrees, insisting the brothers must have shared the suit, with Adrian sending Tom to the house knowing what would happen.
In an attempt to get Adrian to confess, she meets him at his house to discuss her pregnancy while James listens in on a wire. She agrees to mend their relationship, but only if he confesses to being the invisible figure. Adrian insists Tom did kidnap him, claiming that the experience changed his outlook on life and how he treated her in their relationship. When she begins to cry, Adrian alludes to former abuse using similar phrasing to that of the invisible figure. Smiling, Cecilia departs to use the restroom. Moments later, the room's security camera captures Adrian seemingly committing suicide. Cecilia returns and, apparently distraught, calls the police. Out of sight of the security cameras however, she silently taunts Adrian; having retrieved the spare suit she hid earlier to kill him.
When James arrives and asks what happened, she confirms what the camera saw. He spots the suit in her bag, but accepts her story and allows her to leave. Cecilia leaves the house with the suit, in relief.
