Chicago med brother on duty

Between saving lives and protecting family... some lines aren't meant to be crossed.
Dr. Dr. Will Halstead is used to chaos. Long shifts, impossible cases, and patients who don't always make it. It's the job. He can handle that.
Until Bethann Halstead walks into his ER.
She's not just another patient.
She's not just another cop from Chicago P.D..
She's family.
Jay's little sister.
Stubborn. Fearless. Always running toward danger-even when she shouldn't.
And now... she's the one lying on his table.
As cases begin to collide between the streets and the hospital, Will finds himself caught in the middle-torn between being the doctor who follows the rules and the brother who would break every single one to keep Bethann safe.
Because the deeper she gets into Intelligence, the more dangerous it becomes.
And when one case spirals out of control...
Will is forced to face the one thing he can't fix with medicine:
Losing her.
In a city where every second counts and every choice has consequences, Will will have to decide-
Does he save his patients...
or does he save his family?
