Louise Lancaster - approaching 60 - received one of Britain's longest ever jail terms for peaceful protest, in July 2024.

She served part of her sentence in HMP Bronzefield, the UK's highest security women's prison, alongside some of Britain's most notorious killers.

Louise was one of five Just Stop Oil activists involved in bringing much of the M25 to a standstill in November 2022, and has taken part in several other high profile acts of direct action climate protest.

The judge, in sentencing Louise and a number of co-defendents, told them:

"Each of you has some time ago crossed the line from concerned campaigner to fanatic.

"You have appointed yourselves as the sole arbiters of what should be done about climate change, bound neither by the principles of democracy nor the rule of law."

Journalist and producer Patrick Steel has been following Louise's story for several years, and has intimately recorded access to Louise, and her family and friends.

In this documentary, Patrick explores Louise's transition from law-abiding Middle England mum and special educational needs teacher, to law-breaking direct action eco-activist, and criminal.

Has Louise indeed 'crossed the line'? Are her actions a heroic self-sacrifice for the greater good of tackling climate change, or are they damaging and reckless fanaticism?
