When pirates steal some of Voyager's technology, Janeway and Tuvok search their home world and discover her holographic Leonardo Da Vinci who helps them in their search.
Harm and Mac defend a former Navy SEAL, now a homeless man, but still a highly trained killing machine, who is accused of using excessive force in killing three men who tried to hold up a convenience store.
It seems like an open-and-shut case of triple homicide until Harm and Mac discover that the former SEAL, Paul Bauwer acted instinctively at the store as he sought to protect a young boy -- who happened to be his estranged son but didn't recognize him. Bauwer, embarrassed by his own vagrancy, wants to keep his identity a secret from his son. As a result, Harm and Mac must devise a successful defense without divulging their client's relationship to the only witness to the incident, while at the same time proving that Bauwer acted in an appropriate manner.
