In Thursday (June 18) evening's episode, North West Ambulance Service mobilised extra resources to deal with the thousands of visitors flocking to Liverpool for the Grand National.
What happened in last night's episode?
At one point in the documentary, police called for an ambulance after two women who were so drunk they 'couldn't walk' left a baby with head injuries and another needing medical attention.
The officer explained that they had tipped the pram over, causing one of the babies to knock its head and face on the floor.
The policeman said on the phone: "Hello it's Merseyside Police, can I request your attendance please? We've got two drunk females in a car park.
"Both of them can't walk. And then there's also a baby that's injured. One of the females has tipped the pram up in the car park and the baby has hit its head and face.
"And there's another child, but I don't think there's anything wrong with that one."
Speaking to an ambulance crew member, the call handler said the injured child was two years old.
One of the paramedics said, sighing: "That's a bit rough that, isn't it."
When they arrived, the police were on the scene. They asked the child's mum what happened and she said: "Nothing, he fell out the pram hours ago but he's... he's fine.
"He didn't fall out of the pram, he fell into that." She pointed to something at the bus stop where they were sitting.
A paramedic told her: "I don't mean this in a disrespectful way at all, but the grazes and the bumps he has [are] inconsistent from just hitting that."
The police then revealed that CCTV footage showed both children had fallen, not just one.
Taken into custody
When the paramedic asked the second mum if her child had fallen, she denied it - so he informed her they had the incident on camera.
Police took both mums into custody, while paramedics whisked the children to Alder Hey hospital.
One of the paramedics said afterwards: "Makes you a bit angry, doesn't it? Do you get angry thinking these two poor kids who can't even fend for themselves? And both mums... it's two o'clock in the afternoon.
"But we've done our job and both children are safeguarded. They're currently under police protection."
Furious viewers reacted to the scenes on Twitter.
What did viewers think?
One said: "What the? Drunk in charge of babies? Omg! And chucked them out of their prams. Disgusted. #Ambulance."
Another tweeted: "[Bleeping] livid watching #Ambulance! Those two mums getting drunk in the middle of the day and their kids getting injured whilst in their care! Absolutely livid!"
A third wrote: "Watching @BBCOne #Ambulance two injured babies, two drunk mothers. Makes my blood boil #safeguarding #irresponsible."
Unbelievable. Poor, poor kids.
Someone else put: "God almighty, what is this world coming to that two mothers can get drunk and injure their children, albeit accidentally? #ambulance."
A fifth said: "Being so drunk that you TIP your CHILD out of their pram. And then LIE TO THE AMBULANCE CREW and say they DIDN'T FALL is absolutely [bleeping] disgusting #Ambulance."
"Drunk and in charge of a baby," said another. "Unbelievable. Poor, poor kids. #Ambulance."
