The Arderns start their time-travelling adventure running a Victorian corner shop, discovering how life behind the counter reflects two decades of incredible social change.

The Arderns continue their time travelling journey in the '20s, '30s and '40s. From Izal loo roll to powdered eggs, they learn how life behind the counter reflects 30 years of change.

The Arderns continue their time-travelling adventure from postwar rationing to the boom years of the 60s and discover how small shops fought back against bigger grocery chains.

The Arderns adjust to 1970s life, a time when supermarkets had become Britain's shopping destination of choice and corner shops were beginning to feel the pinch. The family's experience begins with a grand opening designed to compete against the onslaught of the supermarkets. While Sam dons his chicken costume to drum up trade for the shop's 'cheap cheap' prices, the Lord Mayor of Sheffield cuts the ribbon to open the doors. But as a newly self-service operation, Dave must completely transform his approach to keep the tills ringing.

After 100 years running a corner shop in Sheffield, the Arderns continue their time-travelling adventure by exploring how local shops continue to thrive in the 21st century.
