Idyllic in nature, the concept of living a scaled-down, simpler, off-the-grid life has gained popularity in recent years, but the initial results for many budding homesteaders have been disappointing. The learning curve is steep, especially in the most dangerous and isolated locations across the country. Many families are not equipped with the skills, experience or knowledge of how to grow food, find water, harness power or deal with the threat of predators. In "Homestead Rescue," craftsman and survival expert Marty Raney -- joined by daughter Misty, a farmer, and son Matt, a hunter and fisherman -- attempt to teach these families the essential skills on how to survive -- and thrive -- in the wilderness. Because sustaining a homestead through hunting, fishing, gardening, building upkeep, security, and problem solving is a full-time job. At the conclusion of each episode, the rookie survivalists decide to either tough out their first year or pack up and return to civilization.

Everyday people on the cusp of key life inflection points use family history, genealogy and sometimes DNA analysis to help guide them on their journey of self-discovery.

Two top chefs are pitted against one another with a challenge to create extraordinary meals using only the ingredients taken from the fridges of ordinary families. Host Emma Hunter visits a family's home and conducts a surprise fridge raid. Then everything is taken back to the studio where the family's fridge is recreated for both chefs. Once the clock starts, the chefs have 45 minutes to get dinner on the table -- cooking with ingredients they've never seen for people they've never met. When time's up, the family takes their place at the dining room table and tastes each meal, scoring them on look, taste and originality -- without knowing who cooked what. Those results are put aside and the same process is done for another family, but with an added challenge that forces both chefs to adapt to a totally unique culinary crisis. With both families' scores tabulated, the final scene reveals the winner of the "Fridge Wars" battle.
