The NYPD is stuck when none of the students of an English as a Second Language refuse to talk to them. Castle, desperate for inspiration, goes undercover as a French-Canadian chef to get them to open up. His agency and Beckett's team help check on the various students who were being helped by the murder victim, a fellow student who was an ex-cop from Central American, as many secrets are unearthed.
