Pulse

Mattie, portrayed by Kristen Bell, decides to visit her friend Douglas Ziegler after he has been unreachable for a week. Upon entering his apartment, she notices his odd behavior, which raises her concern about his mental well-being.

During Mattie's visit, Douglas exhibits increasingly erratic behavior, culminating in a heartbreaking moment where he takes his own life in front of her. This traumatic event deeply affects Mattie and sets off a chain of events that will change her life forever.

In the aftermath of Douglas's death, Mattie begins to investigate his work, uncovering that he had been developing a wireless signal that unleashed a terrifying dark force. This force has begun to affect others, leading to a rising epidemic of suicides.

While searching through Douglas's computer, Mattie discovers a series of ominous viruses culminating in a message asking her, 'Do you want to see a ghost?' This moment marks her first encounter with the supernatural elements at play.

After accessing the mysterious webpage, Mattie sees both herself and her surroundings mirrored on the screen, along with ghostly figures. This revelation becomes a horrifying introduction to the net creatures that are now hunting humans.

As the ghostly invasions escalate, Mattie feels the personal loss of her friend Isabelle, who falls victim during a chilling encounter with the creatures. This loss intensifies Mattie's resolve to understand and combat the unfolding horror.

Mattie traces the computer back to its original owner, Dexter, who is initially hesitant to engage but soon acknowledges the danger they face. Their partnership forms a crucial alliance as they seek to confront the terrifying force together.

While dealing with the growing crisis, Josh discloses the project he and Douglas were working on; a communication network that connects people but also is the source of their torment. His fear leads him to isolate himself, illustrating the overwhelming paranoia gripping them.

In their fight against the cyber-creatures, Mattie and Dexter devise a plan to deploy a virus created by Josh to collapse the network. Their urgency mounts as they face the disintegration of their world around them.

Mattie and Dexter venture into the now-sinister environment of Douglas's building to execute their plan. As they make their way to the basement, they encounter a host of horrifying cyber-creatures determined to stop them.

During a tense moment inside the building, Mattie is nearly consumed by the ghostly predators but is rescued at the last moment by Dexter. This moment bolsters their resolve, reiterating the importance of their mission.

After navigating through the dangers, Mattie and Dexter successfully reach the central modem in the basement. They inject the virus into the system, leading to a tense reboot that threatens to release the dark powers once more.

With the connection to the outside world reignited, Mattie and Dexter flee the now-desolate city, witnessing the ghostly transformations of their environment. A military radio broadcast warns them to find refuge, indicating the broader collapse of civilization.

As they spend a grim night in their vehicle, they face one last assault from a terrifying four-armed creature. This encounter tests their survival instincts as they fight to escape the violent remnants of their former lives.

Ultimately, Mattie reflects on the vast changes to their existence, recognizing that humanity has been thrown back into a primitive state. The struggle continues as survivors and the ethereal beings are locked in a new battle for existence.
