Finn, a rugged young outdoorsman, and his dog head out at sunrise in hopes of catching that big fish. Before Finn can enjoy that first sip of morning beer his lure is rocked by what he can only imagine to be his dream catch. After exhausting a few expert strategies, that demolish most of his fishing gear, Finn realizes he may be dealing with something that doesn't belong in this lake. Improvising fast, Finn attaches a hook to the chain from his anchor as a finally strategy. He finally hooks this invisible force which immediately rips the tin boat and it's two passengers across the lake and settles in a desolate cove. Finn starts up the boat and attempts to pull the creature but the small motor is no match for whatever is down there. A sensible human would unhook the chain and go home but the fantasy of this catch drives Finn to pull out his homemade scuba gear and spear gun. Finn jumps in to the water and cautiously follows the chain down into the depths of the dark lake. The chain leads him in to a small natural rock tunnel. After a brief hesitation, Finn takes a deep breath and slips through to the dark hole. Moments later Finn surfaces and discovers that he is in a dark cave up to his waste in warm water. Using the flashlight on the end of his speargun he surveys the steamy cave and it's rocky walls until his light lands on something he cannot explain. A creature, half in the water, stares back at him. A creature with gills, scales and spikes on it's head but with very human eyes. Before Finn can fully examen the creature it dives under the water only to resurface moments later behind him snarling and standing upright. He spins and shoots the spear gun, which misses and bounces off a rock. Finn struggles for his life as is dragged down to the bottom of the lake screaming, leaving his dog alone on the boat. Moments later Finn comes gasping to the surface, clammers in his boat and drives away. The hybrid fish creature surfaces to watch it's new prey disappear in his tin boat across the lake where he is safe....For now.
