On a busy motorway in the north west, the Highways England team is tasked with rescuing a family broken down on the hard shoulder in thick fog.

The emergency services are stretched to the limit as Storms Doris and Eleanor hit the UK, with 90mph winds taking drivers by surprise and putting Highways England traffic officers under pressure, while South Central Ambulance paramedics are called out when 12 migrants are found in the back of a lorry in sub-zero temperatures. Meanwhile, the Stornoway Coastguard's helicopter scrambles to rescue a climber who fell from 70ft cliffs precariously close to the sea.

In Glasgow, vehicle technician Mark rushes to help a driver who has broken down on the hard shoulder of the motorway, while Kevin and Rob of a heavy recovery crew have their work cut out freeing lorries that have got stuck in snow on the A1M in the north-east of England. A school is forced to evacuate its pupils when Storm Caroline lashes the Orkneys, but one of the vehicles breaks down by the sea wall with 33 children on board.

In the week that Storm Emma hits, the UK's road network is brought to its knees. The heavy road team get to work helping a food delivery truck which is stuck in the snow. Cameras also follow events at a local shop which has run out of food.
