Lois follows a trial about a possible killer, Eugene Laderman (Todd Susman), who she believes is innocent despite he is convicted of killing Henry Harrison (Paul Gleason), the husband of Eugene's lover, Lena (Jennifer Savidge). Eugene escapes and hides at Lois' apartment while Lois tries to prove his innocence. Lois and Clark's investigation leads them to discover that Lean is acting strange for someone who grieves her husband and lover's conviction while at the same time, a virus called "The Ides of Metropolis" that Henry was working on, takes over all the computers of the country. Eugene is the only one who can find the antidote to it and with the help of Superman, they manage to stop the virus before it is too late. While Superman and Eugene work for the antidote, Lois and Detective Reed (Melanie Mayron) find out that Henry is not dead and along with Lena are behind the virus. When everything is done, Reed arrests Henry and Lena. In the meantime, Jonathan arrives at Clark's house after fighting with Martha because he believes that Martha is having an affair.
