On the second part of his journey through the dark ages Richard Rudgley continues into the age of the wandering peoples, the Volkerwanderung. These Northern people enjoyed a golden age unaffected by Rome and just 30 years after the Romans relinquished Britain, the 'Anglo-Saxons' made their move. The bedraggled legions are in retreat. Walls are pulled down. Mosaics shattered. And yet there never was a people called Anglo-Saxon. We look at the lasting influence of Saxon leaders like Alfred the Great, and his blue print for social justice.

As the landscape of work shifts, do we need a drastic rethinking of social safety nets? Do businesses need offices? Is a 9-to-5 workday valid? Does the nation need a drastic rethinking of the social safety nets? Does America face a 'post-work' era, or will there be increased inequities in how we make our livings?

The 1980s was a time when artists in both the UK and US were delivering powerful social commentary in their songs. Dylan Jones selects some of the finest alternative voices from this era. From The Cure on Top of the Pops at the beginning of the decade to The Stone Roses' debut TV performance in 1989, this episode takes a comprehensive look at the alternative music of an entire era. It also features powerful live performances from Billy Bragg, Tracy Chapman, Bronski Beat and The Selecter. In addition, there are archival gems from Pixies, The Smiths, Suzanne Vega, The Fall, REM and many more.

The way that wars are fought is constantly evolving. In the warfare of today and the future, it's the push of a button rather than the pull of a trigger, bringing disorder without a single soldier setting foot on the ground. The real-world battlefield has morphed from the bloody trenches of the front line into an age of cyber warfare. From collapsing all the infrastructure of a country to changing minds for elections, any threat you can imagine can be done.

We learn as much from victory as we do from loss. We employ strategies to gain the advantage, unconventional methods to overwhelm adversaries. One dedicated force steeped in mystique has always been part of war. Special operations, elite and unseen. Their presence felt by lethal attack. From the biblical era to the future of warfare, the battle environment is reshaped and redefined by special operations. Special Operations soldiers have come out of the trenches and are entering new domains of warfare.

In 2011, a Social Security lawyer named Eric C. Conn and a judge named David Daugherty were investigated for committing massive fraud over many years. Conn figured out that he would get paid a hefty retainer for every Social Security disability payment he managed to get approved, so he and Daugherty (who need quick cash to pay for his daughter’s upcoming narcotics trial – which presumably meant bribing an awful lot of people) came to an arrangement.
In the second episode, Investigators starts to collect evidence against Eric and Judge Daugherty. The whistle-blowers are pressured.
