Roommates and pals John Roth (Josh Hamilton) and Moe Curley (Harold Perrineau) start an adult internet site named InterconX where Jordan Nash (Vanessa Ferlito) is one of their stars.

John has recently gone through a disastrous break-up with his fiancé, and is now obsessed with a woman named Angel, who lives her life on 24-hour webcam.

A handful of people whose lives revolve around internet relationships at an adult web site become entangled in person in this comedy/drama.

On_Line is an early example of transmedia storytelling in feature film by expanding the narrative to other platform and related media.

The design, look-and-feel, animation, programming, and general technologies used in the overall transmedia experience was created by Christian D. Bruun, with development starting in 1999.
