Synopsis

L'équipe de Kate enquête sur la mort d'un chauffeur blindé en transport d'argent. Les premières informations recueillies portent à penser qu'il s'agit des mêmes individus qui opéraient, il y a neuf ans, sur une affaire dont Javier Esposito s'occupait. À l'époque, il était fiancée avec Sonia Ruiz. Ils doivent à nouveau travailler ensemble, malgré les sentiments d'Esposito et le passé de Ruiz. Chez Richard, la jalousie s'installe entre Kate et Lucy, la voix informatisée. Après avoir lu le manuel d'instruction à l'insu de Richard, Kate change la voix de Lucy pour Linus.
