Belle, a sweet girl of twenty summers, and Bob, a sturdy youth of about the same age, go upon a fishing trip. Everything appears to be bright and cheerful until Bob catches a large fish. In the excitement which ensues they lose an oar and in trying to recover it the boat is overturned. Bob, after heroically rescuing Belle, reaches the boat, to which they both cling, drifting out to sea. After drifting for some hours they are sighted by "Sea Wolf," captain of a pirate schooner, who hauls them abroad and immediately proceeds to handle Bob roughly, taking all of his valuables. "Sea Wolf" next turns his attention to Belle. Bob, unable to stand the abuse and insults any longer, rushes madly at the "Wolf" but is overpowered, bound and gagged, and thrown below by the crew. "Sea Wolf" again attempts to attack Belle, who puts up a strong fight, but is not able to combat with the brute's powerful strength and soon falls exhausted. Bob, lying below deck, bound hand and foot, is working desperately to free himself. Espying a cutlass upon the wall of the cabin, after clever maneuvering Bob finally frees himself and rushes upon the deck with the cutlass in his hand. He plunges it into the "Wolf's" side. As he falls, Bob secures his revolved. While he holds the crew at bay, Belle, who has revived, climbs over the side of the ship into a dory. Bob, while the situation is still in his hands, starts to follow her. When "Sea Wolf" is a furious frenzy rushes at him. Bob fires: the "Wolf" staggers and falls as Bob disappears over the side of the ship. After another hard battle against the waves, Belle and Bob finally reach the shore where they offer up a prayer in gratitude for their safe return.
