Psychologist Kate takes on a new client, Colin, who expresses frustration over his wife’s refusal to let him care for their newborn son. As their sessions progress, Kate senses that Colin is hiding something, leading her to take unorthodox steps to uncover the full story.

Colin reveals that his wife, Emily, insists that their son is “only hers” and won’t allow him to help. He shares his suspicion that she might be having an affair with a friend named Toby, who was present at their child’s birth when Colin couldn’t be there. Kate grows increasingly concerned as Colin’s story unfolds, especially when she learns he chose to stay with his mother instead of supporting his wife during labor.

Kate decides to break protocol and visit Emily, discovering a shocking truth: Colin had lied about his whereabouts during the birth. Emily reveals, “He was helping his ex-girlfriend move.” With Kate’s support, Emily decides to leave Colin, taking her son with her.
