The film takes us to the North of England to follow the migration of the black-headed gull down to London. There, the narrator asks viewers to "listen to their gossip", before demonstrating the bird’s flight in slow motion. We see a polecat feasting on gull eggs, and then a man collecting the eggs for human consumption, with the film telling us that they are considered a “delicacy” in London. Indeed, according to the British Trust for Ornithology, around 300,000 gull’s eggs were sold every year in Leadenhall Market in London during the 1930s, when London Visitors was made.

During a three-month period in 1888, a knife-wielding serial killer murdered six women on the streets of Whitechapel. Their throats were cut and their bodies horribly mutilated. He was never caught and his identity remains one of the world's greatest crime mysteries. In the years that have passed since Jack the Ripper's killing spree, many high-profile suspects have been suggested, yet the fact remains that none of them can be placed at any of the crime scenes. Now, journalist Christer Holmgren believes that he has found a suspect who can not only be linked directly to one of the murders but also whose daily routine could be consistent with all the other deaths

Haskell Wexler revisits the themes of his previous work "Medium Cool" on the occasion of the Occupy demonstrations in Chicago in 2012.

Every year, thousands of Antarctica's emperor penguins make an astonishing journey to breed their young. They walk, marching day and night in single file 70 miles into the darkest, driest and coldest continent on Earth.  This amazing, true-life tale is touched with humour and alive with thrills. Breathtaking photography captures the transcendent beauty and staggering drama of devoted parent penguins who, in the fierce polar winter, take turns guarding their egg and trekking to the ocean in search of food. Predators hunt them, storms lash them. But the safety of their adorable chicks makes it all worthwhile. So follow the leader... to adventure!!
