Firefly - Season 01 - Episode 09 - Ariel

The crew prepares to land on the planet Ariel so Inara can renew her license to be a companion…which means she'll be spending several days in a hospital undergoing tests. Without warning, River suddenly rushes Jayne with a kitchen knife in her hand. Jayne backhands her across the room. Later, Jayne tells Mal that if River isn't kicked off the ship, she may sneak up on one of the others during the middle of the night and slash them with a knife. Unsure how to proceed, Mal tells Simon that River must remain in her quarters until further notice. As Mal and Jayne discuss the improbability of finding a job so deep in Alliance territory, Simon steps forward with a proposition. He tells the group that the hospital they're going to is filled with medical supplies that fetch an enormous sum of money on the black market. If Mal and the others can help him get River into the hospital's diagnostic ward, Simon will, in exchange, tell the group where the supplies can be located and how much they're worth. Simon hopes that the hospital's neuro-imager will shed some light on River's condition.Simon outlines the entire plan, which involves disguising Mal, Jayne, Wash and Zoe as medical personnel, who will travel to the hospital in a refurbished ambulance shuttle salvaged from a junkyard. Simon injects himself and River with a sedative to make it look as if they're both dead. Mal and the others fly the ambulance shuttle to the hospital landing strip, where they inform a receiving doctor that they're dropping off two DOA's. The doctor instructs them to take the bodies to the hospital morgue. Once the group reaches the location, Simon and River are revived. Meanwhile, Jayne rendezvous with Agent McGinnis... telling him he's brought two fugitives to the hospital as promised. McGinnis assures Jayne he'll be made a very rich man. As Jayne ushers Simon and River to the imaging suite, River senses that a nearby patient is about to die because the doctor caring for him will make a mistake. Moments later, the doctor - who's actually an intern - reacts when monitors around the patient begin sounding an alarm. Simon steps in, realizes the intern made a mistake, and revives the patient.Meanwhile, an officious doctor instructs Mal and Zoe to follow him. Mal and Zoe grow tired of his attitude and overpower him. As Mal and Zoe access the supply vault and begin filling body bags with drugs, Simon uses the imaging equipment to create a three-dimensional image of River's brain. Simon soon realizes that surgeons stripped River of the filter that keeps human feelings in check. As a result, River feels everything. As Jayne prepares to escort Simon and River out of the hospital, River grows hysterical. Jayne realizes she senses that he's about to betray the pair by turning them over to Agent McGinnis. Shortly thereafter, McGinnis and his men move in and place the pair under arrest. McGinnis double-crosses Jayne and arrests him for aiding and abetting fugitives from the law. When Jayne resists, one of McGinnis' men fires his sonic rifle, sending Jayne into a wall.When Mal, Wash and Zoe show up at the rendezvous point and realize Jayne, Simon and River are late, Mal fears the worst. He instructs Kaylee, who's back on the ship, to screen the hospital for signs of a security alert. The group soon realizes that Simon, River and Jayne were picked up by federal agents. Mal instructs Wash to find a way into the hospital through the back of the building. As two federal agents escort Jayne and the others into a substation, Jayne makes his move. A brutal fight breaks out, and Jayne, with some help from Simon, manages to overpower them. Meanwhile, Wash relays word to Mal that federal reinforcements have arrived at the hospital. But when Agent McGinnis informs two Blue-Gloved Men that River spoke to him and his men, the Blue-Gloved Men use a rod-like device to kill McGinnis and all of his subordinates.As they're pursued by the Blue-Gloved Men, River leads Jayne and Simon deep into the guts of the hospital. As they near a large steel door, they hear a tapping sound. A shotgun blast rips through a lock on the other side of the door. The door drifts open…revealing Mal and Zoe standing on the other side. The crew members returns to the ship with the body bags of medical supplies, where they regroup with Inara. When Mal and Jayne are alone, Mal suddenly strikes Jayne with a chained fist. When Jayne regains consciousness, he realizes he's trapped between the airlock and the ramp…and realizes Mal intends to jettison him out into space. Jayne admits he sold out Simon and River because the money was too good to pass up. Mal then hits some controls and leaves Jayne stranded between the airlock and the ramp. Jayne realizes he's lucky to be alive. Later, Simon injects River with some medication.
