A declining birthrate, shortage of doctors, and a wave of maternity ward closures in rural areas...

In modern Japan, the front lines of childbirth—the very place meant to protect mothers and babies—are facing an unprecedented crisis.

Even perinatal medical centers, responsible for handling high-risk pregnancies, are reaching their limits in accepting emergency cases.

Amid this harsh reality, a secret team is formed under the direct orders of the hospital director at one of Japan’s most prestigious, high-end hospitals in Tokyo.

They are known as “Maternal and Neonatal Emergency Medical Unit.”

Their mission is to save pregnant women with complex circumstances who have nowhere else to go—completely free of charge.

The key member of this team is Aki Mitsui, a highly skilled obstetrician-gynecologist.

Despite partial hearing loss in one ear, she is a self-made specialist who is more obsessed with hearing a baby’s first cry than anyone else.

Can Aki and her team become the last line of defense, saving lives hanging in the balance?

Set behind the scenes of a glamorous celebrity hospital, this medical entertainment drama depicts the fierce struggles of the elite unit as they fight to protect new life!
