COMPLICATIONS centers on John Ellison (Jason OMara, Vegas), a disillusioned suburban doctor who, while still dealing with the emotional effects of his daughters death, unexpectedly becomes a vigilante hero when he intervenes in a drive-by shooting, saving a boys life. When John learns the boy is still marked for death, he's compelled to save him at any cost, even if it means compromising his morals, and sometimes doing the wrong thing for all the right reasons. The series also starts Jessica Szohr (Gossip Girl) as Gretchen, a reckless but capable nurse, Beth Riesgraf (Leverage) as Johns wife, and Lauren Stamile (Burn Notice) as Johns by-the-book coworker, Dr. Bridget ONeil, who finds herself dealing with the aftermatch of his actions.
