Donna, Rebecca, Jack, Lou and Ray all share a similar characteristic -- they're all dead. The team splits up to solve their murders: Brass and Catherine pair up to take on Donna's case, a former cop who was working as a bodyguard; Nick and Greg investigate Jack's death, who was an Iraq veteran that was killed in front of his wife and daughter; Warrick and Sofia take on the case of Rebecca, a former supermodel who died while hiking; and Grissom and Sara pair up to look into the deaths of Lou and Ray whose bodies were found together in Lou's garage.
