The team searches for a young mother with one month to live.

Audrey West was last seen leaving a gathering of fellow cancer patients with Ryan, who crashed the party and stole some of the attendees' prescription drugs. While the team tries to locate Ryan, who is discovered to be the drug-addicted boyfriend of Audrey's hospice nurse, they also want to question Audrey's renowned architect boss, Brian Gaghan, who accused Audrey of stealing files and blackmailing him. Meanwhile, Vivian finds herself flooded with disturbing memories of her own health crisis.
