Caleb’s seaside wedding goes straight to disaster — his bride Sloane only tied the knot to get her claws on his father’s old family home. Halfway through the ceremony, a 100-foot giant octopus named Maren rips the boat apart and drags Caleb down to the ocean floor.
Lost in the deep, he unknowingly seals a life-bond with Maren. Gills sprout on his neck, their fates are linked as one, and she’s even carrying his child. The kicker? Maren has waited 50 years to find her long-lost love — who’s actually Caleb’s own 70-year-old father.
When debt-ridden Sloane digs up the truth, she sells Maren out to a ruthless sea-monster hunting outfit. Their family home burns to the ground, Maren is captured and barely hanging on. Caleb risks everything to break her free, but the final showdown looms on the open water. No one can guess how this half-century-old misunderstanding, and the fatal contract binding them, will really end.
