The CSI's investigate the death of a wealthy family's nanny, found by the family daughter whose feet were covered in the nanny's blood. While talking to the son in the family, Calleigh and Delko find out that the nanny was quitting, but they also find some irregularity in her bags. Later on, while searching a suspect's car, the family notices that they have been robbed, leading Horatio to think the nanny "died for the money".
