On Christmas Eve two gunmen with silenced pistols kill a Navy captain in the doorway of a hotel room; Gibbs and company investigate; in the room Gibbs receives an unusual call on the landline telephone, which the gang pursue; Gibbs, Tony, and Ziva visit a mall and find Emma, the woman friend of the victim, who is a pregnant Marine first lieutenant, and who says that she's the real target. Meanwhile, back on the ranch, McGee and Abby figure out why attention turned to Emma and her unborn child; then a Russian bad guy turns up at the mall, but the gang and Barney Fife handle him. In the chat room Tony and McGee use an unconventional method by which to obtain answers. Gibbs, Ziva, and Emma have trouble with their car, and Emma has trouble of her own. Two more Russians show up, so Ziva looks after them while Gibbs looks after Emma and her child. Tony and McGee help. Everything works out. Palmer talks with his future father-in-law, and Tony talks with Gibbs.
