Clarke Griffin is extremely good in a crisis situation. She's in fact pretty much addicted to the serenity she feels every time after cleaning up the mess at work. Flatline is the last thing she wants to see on the monitors in the ER, yet her personal life happens to be exactly that... A flatline. It's not until her roommate's girlfriend moves in with them that she starts to realize that she might be finding herself in the middle of a mess she's not so sure she wants to clean up.
