Without a Trace - Season 4 Episode 6
Viuda Negra

After James Costa is kidnapped after enjoying a night out with his wife in Mexico, Danny and Jack go in at the request of James mother-in-law, but find that between the Mexican authorities and the grieving wife, no one is too willing to help them. While Vivian, Sam, Martin and Elena work the case back in New York, Jack encounters resistance from the locals, and it is only with Dannys help speaking Spanish that they are able to get much of the information they need. The team soon becomes suspicious of Lucy Costa, convinced she knows more about her husbands disappearance than she is saying.
