Allison, a pre-law student and mother of three, discovers that she is able to help the helpless, but not by using her law books.

Desperate to convict a serial killer Devalos calls in Allison to help with the jury, giving her the opportunity to prove herself.

Allison's dreams are proven once again to be based on reality when Devalos instructs her to work with a detective who believes a handful of deaths involving newly weds is being committed by a serial killer and not the murder-suicides they are staged to look like. Meanwhile, Joe is faced with the possibility that he may loose his job.

Allison is convinced that a witness has given a bogus description of the man who killed her fiance and is determined to track down the real killer.

Allison is convinced Joe is having an affair while at the same time Devalos asks Allison to lie under oath for him.

When Devalos introduces Allison to a good samaritan that is helping his case out, Allison senses only evil from him. With no evidence to back up her intuition, Joe is convinced that Allison may be pregnant and the vision is a hormonal side affect.

Allison has to convince Devalos that a suicide is actually the result of a completely different crime, which forces Allison to interact with Larry Watt (Conor O'Farrell), the same lawyer that tried to expose her as a psychic weeks earlier.

Allison is disturbed when she has a dream about the death of her step-brother, but is more concerned with his mental health when he shows up on her doorstep.

When Ariel, Allison's oldest daughter, starts dreaming about a dead little girl, Joe and Allison must decide how to handle their child's new, sometimes disturbing, dreams. While Allison tries to help Ariel make sense of her dream, Joe would prefer to shield his daughter from the truth and blame the visions on nightmares.

A recurring dream keeps Allison from getting sleep and begins to interfere with her life and her job.

When Allison becomes sick, her medicine heightens her abilities and unravels a murder case from the 1960s involving a Hollywood couple.

Devalos decides that Allison should view an execution of a death row inmate so she can see the seriousness of her job. Meanwhile, Ariel makes a new friend at school, but Allison fears the friendship will lead to heartbreak for her daughter.

When a woman goes missing, Devalos and Scanlon call in Allison for help in disproving the husband's alibi. However, what Allison discovers could put the lives of hundreds of innocent people at risk.

Allison discovers that an innocent man has been in prison for 15 years, and the real murderer may be unstoppable.
