When private detectives Heaven and Garrick are approached by a polygamy escapee to find her long-lost missing child, they must keep romantic entanglements aside and infiltrate an underground prostitution ring run by ruthless extremists.

After solving the case involving the murder of the mayor of Los Angeles' daughter and actress Lauren Jenkins, Heaven and Garrick started a private investigation business together and mutually agreed to keep their previous romantic relationship strictly professional.

One morning, Brook Ambers, a well-known rich widower, enters their office. After some hesitation and skepticism, Brook begins to open up and goes on to tell Heaven and Garrick about her heartbreaking childhood. Brook goes on to explain how she gave birth to a baby at the age of 13 that was taken straight from her womb at birth and how she did not know the gender of the child. Heaven and Garrick agree to the task of finding this child who would now be an adult.

While surveilling the polygamy compound, Garrick is shocked to see a former colleague, LAPD Detective Gwen Pratt, entering the premises. Unsure of why Detective Pratt is there, Heaven and Garrick both agree to go talk with her.

When speaking with Detective Pratt, Heaven and Garrick are surprised to find out that Pratt was a runaway from the same extremist group when she was young.

Heaven, Garrick, Pratt, and an FBI agent team up to infiltrate the compound by going undercover to bring down this extremist underground prostitution operation while reuniting Brook with her son.
