Proof Through the Night (S01E05)

A Russian spy learns that Soviet scientists have created a deadly serum capable of killing anyone who comes into contact with it. He swipes a vial and reaches out to his friend Archangel for assistance in fleeing the country with his family. In response, Archangel sends Hawke and Santini to carry out the rescue. However, Airwolf can't accommodate the extra weight of the passengers unless all her weapons are removed, leaving the powerful helicopter vulnerable.
