It's a medical drama with a twist. In the show "Boston EMS", the emergencies aren't scripted, they're real.

The middle of summer means it's time for another fast-paced medical show from my Emmy-Award winning friend Terry Wrong and his team at ABC's 'Lincoln Square Productions'.

Last year, he introduced us to the brave men and women of 'Boston EMS'.

Now he's back with the show's second season, and more of their stories.

The stakes are high and nothing is staged. 'Boston EMS' puts the 'real' back into reality TV.

"For the camera people who are in a moving ambulance at 60-70 miles per hour with lights and sirens going. They are contortionists trying to keep upright, trying to get the footage with one foot on one wall and one foot on another wall," said executive producer Terry Wrong.

The tight quarters yield plenty of great stories, about people at turning points where their lives hang in the balance.

"And, the other thing is to see what kind of a personal journey and honesty the caregivers are on," said Wrong.

We meet one caregiver on his way to an auto accident. Kids were in that car so one of his first moves is to reassure them.

Randy Brinson has a special understanding of what this mom and her kids are going through:

"Because I was involved in something like this and it made me appreciate EMT's and paramedics so I signed up for an EMT class," he says.

Brinson was treated and saved by the same people he now serves alongside.

"It's a very intimate experience. These are neighborhoods they grew-up in. They are of the city and so they feel things very deeply," said Wrong.

It was this same group who helped those injured when the bombs went off at the Boston Marathon, and over the course of the next few weeks, we will get to know a lot more about these dedicated EMT's and what's going on in their lives.

'Boston EMS' premieres this coming Saturday night at 10 p.m. on ABC 7.
