The Freemans--a working-class Catholic family with five kids--are mourning the recent loss of matriarch Liz's alcoholic father and dealing with oldest son Nick's impending departure from the nest. But far more foreboding things may be in store when a mysterious woman pays an unwelcome visit to the funeral.
Three weeks after her father's funeral, Liz, plagued by fear of Eva Morrigan, begins lashing out at her family. She seeks comfort from her priest, Father McGinley, who insists that her worries are delusional.
Trish, the Freemans' younger daughter, is smitten with Malachy, a boy from school. Meanwhile, Liz, knowing that Eva is back in town, grows increasingly paranoid. Little does she know, Eva inches closer to her family each day.
Eva continues meddling with the Freemans, this time targeting Nick by buying his used car, a sale he desperately needs to finance moving in with his girlfriend, Debbie. Noticing Eva loitering outside her house, Liz decides to move the family to another town, much to their dismay.
Liz confronts Eva about her romantic evening with Nick. Later, at Trish's 15th birthday party, an ominous e-card arrives in Anthony's inbox, its upsetting implications creating suspicion among the partygoers.
The long-kept secret about Sue, Nick, and Trish is at last revealed to the whole family, causing feelings of resentment and betrayal. Now that the truth is out, how will Liz and Jack reveal that the woman behind it all is someone their children have already met?
Eva finally has the moment she's forever fantasized about--revealing herself to the three biological children she's been invisible to for so long. But how they each react creates a vast rift within the Freeman family.
Jack is increasingly cagey about the identity of Eva's husband, leading John Paul and Anthony to launch their own covert investigation into the matter. Trish, now living full-time with Eva, is enjoying the gifts her glamorous new mother lavishes upon her.
The bombshell of Jack's bigamy robs the Freeman children of their solid foundation. John Paul reacts to the news by confronting the priest who covered for his father, while the other siblings take more drastic measures to channel their pain.
Still keeping his distance from his family, Jack grapples with taking responsibility for the havoc his actions have wrought. At the Freeman household, a game of truth or dare turns toxic as Trish needles her older siblings about their significant others and inadvertently unearths an ugly truth.
