The Marine Corps returns the remains of a WW2 codetalker to a Navajo cemetery, but a native medicine woman denies that the remains are his. Harm, Mac, Bud, and Harriet investigate. Truth emerges, and Harm proposes an acceptable compromise.

Bud Sr. and Mike (Bud's father and younger brother) travel to Washington for Bud and Harriet's wedding. Bud Sr. leaves insults, injuries, and hurt feelings in his wake; Harriet's mother also causes much discomfort and embarrassment. Bud passes a big career milestone with grace and empathy. A dry cleaner loses Harm's dress whites, but Harm finds them in an unusual place. The girls go to Harriet's party, then Mac bails Harm, Bud, and the admiral out of a DC jail after Bud's party. Bud Sr. skips the beautiful wedding, and Mike arrives late.
