This powerful, one-off observational documentary offers a rare insight into child Thai boxing, one of the fastest-growing martial arts in the UK. Children as young as four or five are becoming the latest recruits to organised fighting, where some people’s attitude is: if you’re good enough to fight, you’re old enough.

Now, Channel 4’s Cutting Edge strand enters the competitive and sometimes obsessive worlds of four families who are investing everything into training their kids to be the best young fighters in Britain.
