Dive into the frigid world of competitive ice fishing, following a tight-knit group of colorful fishermen as they compete against Mother Nature – and each other – every weekend.

With personal bets for bragging rights and derby prizes sometimes reaching upwards of $100,000, these weekend warriors are willing to do whatever it takes to best their fishing buddies, catch the big one and win the money.
