Ahead of the EU referendum, Laura Kuenssberg examines the economic costs and benefits of EU membership in this BBC documentary.
She talks to politicians and business leaders on both sides of the debate in an attempt to find out what leaving could mean for trade and jobs, for red tape and people's livelihoods.
Kuenssberg also looks at what the UK brings to the EU, and what it gets back, before hearing the views of the public on whether Britain is better off in or out.
