The story of Pulse Season 1 begins on a stormy, rain-soaked morning in Miami. A high school soccer team is traveling by bus to a competition, the young players laughing and joking with their coach as the rain thickens, reducing visibility to just a few yards. Suddenly, the coach spots a massive pile-up of cars ahead but cannot stop in time. Swerving to avoid the wreck, the bus careens off a bridge and plunges into the water below. The scene is chaotic and urgent as emergency responders rush to rescue the students and coach, who are then transported to Maguire Hospital, a level-one trauma center where much of the series unfolds.

At Maguire Hospital, we meet the central character, Danielle “Danny” Simms, a third-year resident doctor. Danny is immediately shown juggling the intense demands of her job with the complexities of her personal life. Her younger sister Harper also works at the hospital as a junior resident but is confined to a wheelchair due to a childhood accident, adding a layer of emotional depth to their sibling relationship. Danny’s close friend and professional rival, Sam Elijah, is also a third-year resident competing for the coveted position of chief resident. The competition is fierce, especially with the presence of Dr. Xander Phillips, a wealthy and arrogant doctor with a complicated reputation. Xander is under investigation for sexual harassment, a charge Danny has reported, which creates tension and uncertainty in the hospital dynamics.

The hospital staff includes Tom Cole, a surgical resident who is higher in rank and often dismissive and rude, especially toward Sophie Chan, an intern, and Camila Perez, a new third-year medical student. These interactions highlight the hierarchical and sometimes toxic environment within the hospital.

As the series progresses, a hurricane hits Miami, intensifying the pressure on the hospital and its staff. The storm brings a surge of patients, forcing the doctors to make difficult decisions under extreme conditions. Danny is unexpectedly appointed interim chief resident by Dr. Natalie Cruz, the hospital’s unit founder and a figure of authority and mentorship. This appointment surprises many, given the ongoing investigation into Xander and the usual expectations for the role.

Throughout the season, flashbacks reveal Danny’s past and the complexities of her relationships, especially with Xander, whose behavior and the harassment allegations are shown in conflicting lights. The narrative uses a heartbeat motif and sepia-toned flashbacks to immerse viewers in Danny’s emotional and psychological state.

Key episodes include:

• The opening episode "Abby," which sets the stage with the bus accident and introduces the main characters and hospital environment.
• "Treat ‘Em and Street ‘Em," where the staff must handle the influx of patients during the hurricane, showcasing their medical skills and personal struggles.
• "The Last Shift," a pivotal episode directed by Carlton Cuse, where tensions reach a climax as the storm worsens and the chief resident race intensifies.
• The finale "Kennedy," which wraps up the season’s arcs, including the resolution of the chief resident position and the fallout from the harassment investigation.

Danny’s character arc is central: she evolves from a determined but somewhat overwhelmed resident into a leader who must navigate professional rivalries, ethical dilemmas, and personal trauma. Harper’s presence adds emotional resonance, showing the challenges of disability and family bonds within the high-stress hospital setting. Sam’s rivalry and friendship with Danny provide a counterpoint of camaraderie and competition. Xander’s ambiguous role keeps viewers questioning his true nature and the complexities of power dynamics in the hospital.

The season ends with the hospital staff battered but resilient, having faced the storm both literally and figuratively, setting the stage for future conflicts and developments that, unfortunately, will not continue due to the show’s cancellation after one season.

This narrative unfolds scene by scene with visceral detail: the rain pounding on the bus windshield, the frantic rescue efforts, the tense hospital corridors filled with the sounds of monitors and hurried footsteps, the quiet moments of reflection in the break room, and the charged confrontations in the operating rooms and offices. Each character’s emotional and physical struggles are portrayed with immediacy, drawing the viewer deeply into the pulse of the hospital life.
