Director of Psychiatric Services Dr. Jack Gallagher and psychiatrist Dr. Veronica Hayden-Jones are called to the ER for a psych consult where they meet Melissa Ranier (guest star Nicholle Tom), a woman presenting as seven months pregnant. However, the doctors are informed by the ER physician that the patient's ultrasound did not reveal a baby. When the woman's husband (and OB/GYN) arrives, they find he, too, is under the delusion that his wife is pregnant. Jack must take drastic measures to get to the bottom of the case and help bring the couple back to reality. Meanwhile, Jack searches for his mentally ill sister, Becky, whom he believes is homeless and wandering the streets of Los Angeles.
