I really enjoyed this first season of 'The Pass' Although it takes its initial cue from The Bridge and it's body discovered straddling the border, it soon becomes its own beast. All parts are strongly acted with particular credit to Nicholas Ofczarek who plays the male lead detective, and also Franz Hartwig who plays a suitably unsettling psychopath. Julia Jentsch is the glue that binds them together playing Ofczarek's partner.
This is yet another Euro gem, there are plenty out there.
