Sniper: Bulletproof deconstructs and analyzes the little-known sniper events that have occurred when no other course of action was possible. The people who planned the takedowns, or pulled the trigger, share their techniques and bring to light the many factors that had to be considered in each mission: terrain, wind speed, temperature, elevation changes... all are critical to taking out targets considered bulletproof. A sniper has one chance, one breath, to rise to the occasion and save the day... if they miss, there may never be another opportunity. As these never told before stories unfold, the viewer also learns about the high-tech gear each sniper carries on their classified missions.

Dr George McGavin and Dr Zoe Laughlin set up base camp at one of the UK's biggest sewage works to investigate the revolutionary science finding vital renewable resources and undiscovered life in human waste. Teaming up with world-class scientists, they search for biological entities in sewage with potentially lifesaving medical properties, find out how pee can generate electricity, how gas from poo can fuel a car and how nutrients in waste can help solve the soil crisis. They follow each stage of the sewage treatment process, revealing what the stuff we flush can tell us about how we live today, and the mindboggling biotechnology being harnessed to clean it, making the wastewater safe enough to return to the environment.
