In Japan, "Sempai" is often used as an address and as a show of respect to one's superior.
"Kohai", on the other hand, can be considered offensive when used to address someone directly, as it is "putting someone in their place." Hence Captain John Connor (Sir Sean Connery) effectively insults Lieutenant Webster Smith (Wesley Snipes) throughout the movie.
Sean Connery, Wesley Snipes and Harvey Keitel star, along with Cary-Hiroyuki Tagawa, Kevin Anderson, Mako and Tia Carrere.
This is a high-tech story (at least for 1993) as two cops try to figure out who murdered a woman.
It's Japanese-big business-politics intrigue with surveillance cameras being the key to figuring out a murder.
