Series 1

A glimpse into the lives of the army of night workers who keep Britain running while the rest of us sleep. Today, a team of vets perform surgery on a valuable horse.

A team at Care Call rush to provide emergency support to clients with very different problems, mechanics at the AA work to rescue stricken motorists, and the staff of the Theatre Royal in Newcastle attempt to get one touring show out in time for the big money-spinning panto season.

A team of roadworkers battle against the clock to repair one of the UK’s busiest sections of road before rush hour.

A courier company faces the busiest night of the year, and out-of-hours vets have a sickly pup to tend to.

A radio DJ keeps Newcastle’s insomniacs company, and the city's milkmen enjoy a resurgence in popularity.

An out-of-hours vet practice has its hands full, and for one owner there is an expensive decision to be made. A railway team face darkness and danger against the clock as they try to repair a section of track before the morning commute, and a team at a food wholesaler face delays and disruption.

A mechanic comes to the rescue of stranded motorists, the team at a revolutionary new power station burn rubbish to generate electricity, and torrential rain means a team of road workers struggle to lay new blacktop on a vital stretch of road ahead of the morning rush hour.

A farmer works round the clock to help two of his valuable cows give birth, a locksmith and plumber are called out after dark to two very different emergencies, and the team at Network Rail battle bad weather and failing machinery to get the track open in time for the morning commuters.

Volunteers from Northumbria Blood Bikes supply blood to the air ambulance and transfer life-saving supplies between hospitals. A Northern Powergrid team tackle power cuts, a cheese factory crew keep production going through the night, and markets are bustling ahead of a day of trading.

In Tynemouth, the biggest fish catch of the year is landed with only hours to process it, and refuse collectors get Newcastle’s streets clean before dawn breaks.
