 At a frat party Steve hosts at Casa Walsh, things take a turn for the worse when Steve s two teenage stepbrothers, Ryan and Austin, start drinking excessively in which Ryan passes out and almost dies from alcohol poisoning. When Rush finds out, being arrogant and narrow-minded as usual, naturally blames Steve for the near-disaster. Valerie brings Colin to the party who s between incarcerations. Meanwhile, Tara gets out of rehab and moves in with Kelly, Donna and Clare at the beach front apartment. Also, Kelly invites Greg, a med-student from the rehab center, over to the party and whom ends up saving Ryan s life.
