Every year tens of thousands of Poles attend a nationalist march in Warsaw. It's an event that has the people of Poland's capital city staying indoors.
Since its inception, far-right football fans - or 'ultras' - turn violent against the police, and the march becomes a ferocious battle between hooligans and the state. This year, however, something is different.
A right wing government is elected on the eve of the march. How will this affect this traditionally bloody parade?
