Barney Mullen, the "Sea Rover," is the middle-aged owner of a tramp steamer. In his one appearance he takes on a job to get to a load of gold filigree from Lisobon to Rotterdam. This is dangerous, of course, as Rotterdam is in the war zone. Unfortunately, Mullen's ship is spied on in Lisbon and so once they reach the open waves the ship is threatened by an armored cruiser. Mullen runs for it and uses a fog bank to escape the cruiser, only to be attacked by a bomber (the cruiser's anti-aircraft guns fight it off) and a submarine (which torpedoes the ship once but does not do it in) and a group of mutineers (a fight drives them off, with Mullen leading the way, fists a-flying). Just beyond the Straights of Dover the ship's steam engine blows up, and the crew takes to the life boats. Mullen, being clever, had stored the gold filigree in the boats, and so his cargo gets delivered on time and everyone's happy, including Mullen, who was paid enough for the trip to replace his old ship.
Note: This is a curious attempt to do a comic strip version of Captain Kettle. It does not succeed in capturing the original's charm.
