This episode tells the story of architect Alastair Lansley, whose expensive artistic vision unnerved the engineers.

The engineers and builders are about to hit the biggest deadline on the project so far. The tracks which bring the trains into St Pancras must be moved from the east to the west side of the station, over the course of a single weekend. If they fail, the entire £5.8 billion project will be thrown off-schedule. Meanwhile, Chief Architect Alastair Lansley receives some terrifying news that may prevent him from seeing the project through.

Engineers race to finish the base build of the station. Huge bonuses are at stake and if the engineers don't meet their deadline they could incur penalties of £50,000 a day until their work is finished. For 30 year old engineer Claire Clarr this is the biggest project of her career and a series of gruelling inspections will determine whether or not work on her section is signed off as complete. To add to the pressure Claire's boss Mark Allison delivers news which will change the course of her working life.

With the base build complete, St Pancras must start its face lift. Commercial Director Mike Luddy dreams of creating a new style of station and of transforming St Pancras into a luxury destination in its own right. Instead of fast food outlets he wants to install gastro pubs and fine dining. The highlight will be the longest champagne bar in Europe and a nine metre high bronze statue which he hopes will be an iconic centrepiece for the station.

A team of spin doctors and marketing gurus have to sell Commercial Director Mike Luddy's vision for St Pancras station. They need to convince press and public that a place synonymous with prostitution, drugs and violent crime has been transformed into the chic destination station for Europe. But deadlines are slipping and the picture looks very different on the ground. The builders are behind schedule, the 60 shops may not finish work on time and there are critical problems with the cherry on the St Pancras cake - a 9 meter statue specially commissioned for the station. And with the station opening in just a few weeks time and Eurostar already selling tickets from their new destination will St Pancras be ready in time?
