Emergency!

Insomnia (3x8)

:

A boat has an explosion aboard en route to the marina. John obsesses about the lack of night runs and can't sleep. A man and his son are injured when they swerve to avoid a dog. Doctors race against time to save a marijuana smoker dying of an unidentifiable malady. A worker is pinned in a loading dock by a semi. A man child fall into a gravel pit.
