After Ana Martinez "expires" as hospital bureaucrat Linda Garran terms it, Parkfield contacts police about her death, and Detectives Braun and Baldwin are assigned the case. In their first meeting with Garran, hospital lawyers, and a local politician, Braun and Baldwin are confused as to their role. Hospital reps act as if they're being thorough, but they're really hoping for this to be swept under the rug. However, the detectives intend to get to the bottom of the mystery. They're surprised to learn Mrs. Martinez died seven weeks ago and that her body has been cremated. That authorities weren't contacted sooner is the first sign of a coverup. 

They discover that one of the nurses, Cullen, had a criminal complaint filed against him. When they make an inquiry, they learn charges were dropped, but there's a note stuck to his file with the word "digoxin" on it. They only realize Ana died by insulin overdose because Garran happens to leave the room, momentarily freeing them to show Amy the list of meds she'd been given, which was technically off-limits for questioning. Amy identifies the double medication error, which she says is extremely rare. 

Braun and Baldwin have to pressure Garran to produce the records of their internal investigation, and when it comes, it's not the boxes full of paperwork Baldwin expects but a single folder. Strongly suspecting Cullen, Braun calls former employers, none of whom will talk once they hear his name. When Amy confirms that PYXIS keeps receipts of all medication withdraws (detectives have only been given page nine), Braun and Baldwin are certain the hospitals are purposefully hiding the truth.
