A psychotic estranged wife attempts to sabotage her husband's new romance by turning her children against his lover in this thriller. Jude (Jamie Lee Curtis) had abandoned her husband Robert (Peter Gallagher) and their three sons several years earlier. Unfortunately, now that Robert has filed for divorce after falling in love with Callie (Joanne Whalley-Kilmer), the sweet-natured assistant principal at his son's school, Jude is back for revenge. At first she merely tries to convince the children that Callie is an intruder on the rightful family, but the psychotic Jude's actions soon turn dangerous, as she attempts to frame the educator for assault. Things become particularly sticky when she tries to win over her 12-year-old son Kes (Luke Edwards), involving him in a potentially deadly scheme. Director Yves Simoneau borrows from numerous other stalker dramas and attempts to ratchet the action to a feverish pitch in the conclusion, but Jude's behavior remains unbelievable, and most critics found Mother's Boys an unconvincing, often over-the-top psychodrama.
