April joins handsome paramedic Matthew for a drive-along. They pick up a 10-year-old kid who is in critical condition after a hit and run. April knows the boy will die before they make it to the nearest ER. She calls Jackson for help. Since Seattle Grace is no longer a trauma center, Owen and Alana say they'll be liable if anything goes wrong. That's why a team of rogue docs sneak the patient in after prying open the closed ER doors. Unfortunately, all the equipment and medicine has been cleared out of the area.
Jackson, Meredith, Cristina, Alex and a gaggle of interns work to save their patient while keeping all unfriendlies at bay. The paramedics also pitch in by offering equipment from their rig. Without a nurse on hand, Jo is forced to show off her math skills to figure out proper dosages. Derek is wrangled into the mix because his hospital code is needed to access the proper meds. He steers some reps from Pegasus away from the hot zone by offering to show them a real brain. Cool!
Despite Derek's best efforts, he can't keep Alana and the Pegasus folks away from the old ER. Jo screams that they have to move the patient. April is freaking. What if the kid dies?! Alana and the others make their way into the ER. Much to Derek's surprise, the place is empty. All is well until Alana sees a few drops of blood on the floor. She's off in a huff to find out where it came from.
