Boys from the Blackstuff (1982)

S1E2 Moonlighter

Struggling to feed and clothe his four children, Dixie takes a shady job as a night watchman at the docks. He quickly learns that a lone man on a ship after dark can only look the other way while a gang of thieves helps themselves—but if the missing cargo is discovered, what will he tell his boss, whose small security firm is barely staying afloat? Meanwhile, the petty bureaucrats at the D.O.E. launch a covert operation, and Dixie's wife Freda is too terrified to answer the door.
