S3·E32 Go Home Dead Man

Williams is a pilot who works for Scandinavian Export, flying by night to deliver unknown shipments to somewhere in the Arctic. Feeling something's fishy, he tries to quit but is strong-armed into making another flight. His bosses are smugglers and they plot his "accidental" death. When their attempt to murder him on a train fails, they plan an explosion with the help of the woman he believes is in love with him.
