Patrick Moss is the son of Yolanda Moss. In a concert downtown, Patrick is having truoble breathing as a fire breaks out. Firefighters are trying to put out the fire downtown, when Captain Lance Carlyle and Gwen Richards find him trapped. Lance goes down to rescue him. Gwen calls for Lance as the building is creaking. Another firefighter comes and they together pull Patrick from the hole; Patrick has Lance's mask, and they hurriedly pull Lance from the hole as well. Lance is not breathing. Dr. David Lee and Dr. Miranda Foster report to the ambulances as they start to treat the victims. They have Patrick. David and Miranda are treating Patrick as Patrick explains that when he tried to open the door, the gloves melted to his hands. Patrick has a lot of burned scar tissue on his chest, and he is having truoble breathing. Patrick's mother walks in. David explains to Yolanda, Patrick's mother, that they cannot give Patrick medicine for the pain because he may have taken drugs, becuase if they did, Patrick would stop breathing. David is disscusing with Dr. Lisa Reed the possible reasons why Patrick is having trouble breathing; his lungs are okay; maybe it's drugs, or his skin is tightening around his chest. Lisa says she'll check around to see what kind of drugs there were at the concert. Yolanda talks with her son, but Patrick still says that he didn't take drugs. Yolanda then talks with David, telling him that Patrick took rock cocaine when he was fifteen, the same as her. They got clean together, and have been ever since. David checks in on Lisa, and the results for drug usage are negative. It does not explain why Patrick still has track marks. Lisa tallks with an EMT, who tells Lisa that the track marks were from the IV's she put into Patrick's legs. David and Lisa share with Yolanda that Patrick didn't take drugs. Patrick is having trouble breathing again. Lisa and David believe that it is because of the scar tissue tightening around Patrick's chest. They put him under to reduce the strain by surgeory, and a nurse takes Yolanda outside. Patrick is still not getting enough oxoygen. David orders another study of Patrick's blood. Lisa orders an ultrasound, and it looks like blood is building up in Patrick's heart, making it hard for Patrick to breathe. David inserts a syringe into Patrick's heart. Instead of blood, fluid is in the syringe. Lisa and David are certain that there is a disease causing Patrick's breathing problem. From his mother's information, Lisa says that it might be joint inflamation. It turns out that Patrick is suffering from an auto-immune disease that effects the lungs, making it hard to breathe. David orders the nurses to give Patrick medication for the disease. Patrick is awake and well. Yolanda hugs David for saving her son.
