The sun glows over the hot asphalt. The air conditioning fails in the train carriage, Bluetooth speakers compete with each other by the river and a demonstration brings the trams to a standstill in the city centre. A couple crawls into the fan-cooled togetherness, a family escapes into the idyll of nature and a group of police officers languishes in the van. While the ice melts and tempers flare, no one sees that the water is already up to their necks.
