Pam Hupp, Betsy Faria's close friend, is the last person to see Betsy alive after dropping her off at home on the night of her murder; Betsy's husband, Russ Faria, makes a distraught call to 911.

Pam becomes a source of support not just for Betsy's family, but also for law enforcement and District Attorney Leah Askey as they build their case; Russ hires Joel Schwartz, a top criminal defense attorney from St. Louis.

Pam gets her 15 minutes of fame when DA Leah Askey calls her to the stand as a witness for the prosecution even as Joel Schwartz tries to poke holes in the case against Russ.

As Russ' new trial looms ahead, Pam faces money troubles, a relentless "Dateline" producer and difficulty caring for her sick mother; DA Leah Askey realizes Pam may not be the star witness she thought; Joel Schwartz makes breakthroughs in his case.

Pam gains notoriety once the "Dateline" episode airs; as she squares off against Betsy's daughters in a civil suit for the insurance money, public opinion turns against her; Leah Askey finds her seat as District Attorney challenged by Mike Wood.

Pam goes to shocking and absurd extremes to extricate herself from the web of lies she has spun; some measure of justice, redemption and hope is finally found.
