We follow Pete McCleave as he travels 6,000 miles to his ancestral home of Macau in an attempt to extend his life. The dad-of-two was diagnosed with rare blood cancer myeloma in 2017 and given just seven years to live. His best hope is a stem cell transplant - but his mixed heritage has made it difficult. DKMS, the largest stem cell registry in the UK, says four out of 10 people looking for an unrelated matching donor worldwide are not able to find a match. https://www.dkms.org.uk/ (Visit their website to sign up to the register).
