Liz Parrish wants to cure ageing.

She believes that ageing is a disease. She says regulation is stopping researchers from saving lives. But Liz won’t be stopped.

In 2015, her company flew a patient to Colombia for the first treatment of its kind in humans: gene therapy to reverse biological ageing.

Remarkably, they claim it worked.

If that’s correct, then why are we still dying of old age?

Journalist Frank Swain embarks on the hunt for the true story behind this controversial human experiment.

After Bioviva’s big announcement, scientists and journalists scramble to figure out the truth. Who is the human guinea pig and what has happened to them?

Where did BioViva get their new drug? Frank ventures into the hills of the Sierra Nevada to find out.

Five dementia patients travel to Mexico for an experimental gene therapy. Frank discovers documents that show Bioviva’s Chief Medical Officer has a chequered past.

Desperate to get some real answers, Frank travels to Bainbridge Island in Washington to meet Liz face to face.
