What kind of guy is Tom Paris (Robert Duncan McNeill) exactly? Keeping in mind that his character was introduced on
Voyager as a pilot thrown out of Starfleet for covering up an accident, then later jailed for his (bungled) role as a Maquis mercenary, one might say he's a heel seeking redemption at
Voyager's con. But "Ex Post Facto" suggests he's still a scoundrel at heart.
When Paris and Harry Kim (Garrett Wang) dine in the home of Banean scientist Tolen Ren (Ray Reinhardt), Tom becomes distracted by the restless beauty of the man's wife (Robin McKee), leading to an illicit liaison that ends with the murder of Ren. Paris is accused, found guilty, and uniquely punished by experiencing Ren's death, from the victim's point of view, every 14 hours in his mind. It's up to Commander Tuvok (Tim Russ) to get to the bottom of the mystery.
There's lots of controversy about the value of this episode. One camp believes Paris is unfairly stereotyped, that the film noir elements in the script and visual style are perfunctory, and that the story is a rehash of The Next Generation's "A Matter of Perspective." Others, particularly writer Michael Piller, believe it to be a blend of detective drama and The Twilight Zone. In fact, all those assessments are valid: the episode is both overly predictable and dark. --Tom Keogh
From the Back Cover
Kim and Paris visit the homeworld of the Baneans, a people at war with the nearby Numiri. There they meet with the head of military science, Tolen Ren, to discuss potential scientific advances that may help Voyager find a faster way back to Federation space. Ren's wife, a much younger woman named Lidell, does not make Kim or Paris feel very welcome. Later that night Ren is killed and Paris is blamed for the murder. His Banean sentence: to relive the violent moment of the crime from the victim's perspective for the rest of his life. Only after Tuvok mind-melds with Paris is it discovered that a shorter man had murdered Ren. Just who that man was is only detected by Ren's faithful watchdog, Leeka.
