When a mother-son bond breaks, a call to the emergency services beckons in the first of a new run of 999: What’s Your Emergency.

A recent study found that a mother is the most powerful factor in determining what kind of man her son will become.

As the sixth series of this behind-the-scenes documentary begins, Wiltshire’s emergency services are called out to incidents where blood may be thicker than water, but it doesn’t stop
