Big Fish, Texas follows Galveston's Guindon clan as they try to keep Katie's Seafood Market, their family business, growing and thriving at all costs. A homegrown enterprise built both on land and at sea, Katie's challenges appear from all sides, and this tightknit group takes on all comers. On the water, they battle against long days, even longer nights, a sea full of predators, and Mother Nature's whims. At home base, they struggle to juggle surpluses, shortages, and orders while also processing a quarter of the Gulf's deep-water fish and spearheading initiatives to preserve their fishery. But no matter how busy the business keeps them, at the end of the day this is a family built on old-fashioned values, and they'd never miss an opportunity to get together for a good laugh and a home-cooked meal.
