Anyone else watch this last night? Two episodes every Saturday, eight in total.
Set in Copenhagen, masked baddies hijack a tube train and kidnap 15 passengers. They take them off the train and through the tunnels to a new station being constructed under the Cathedral. They demand 4million euros - which seems cheap - and the police teams above ground try to work out how to free the hostages. Lots of nice flats, glamourous Danes and a fair bit of suspense too.
