Saving Our Nurses (2020)

S4E16 Silent Service

Harm and Mac are thrust into an uncomfortable situation when they are called to investigate an international crisis involving a nuclear submarine. As tensions rise between them, the cramped environment of the sub only intensifies their irritation with each other. Their attempts to avoid interaction prove ineffective, as they need to collaborate to uncover the reason behind the submarine surfacing far off its planned route and colliding with a Norwegian boat during a regatta. At first, it appears that an E-coli outbreak, leading to reduced crew numbers, is to blame for the mishap. However, as more health issues emerge on the submarine, Harm and Mac begin to suspect that something more sinister might be at play.
