text: Plot After years of pursuing Cullen Crisp, an infamous drug lord, LAPD detective John Kimble arrests him for murder after a girl named Cindy witnesses Crisp murder an informant after getting information regarding the whereabouts of his former wife, Rachel, who he claims stole millions of dollars from him before fleeing with his son, Cullen Jr.
  Partnered with former teacher-turned-detective Phoebe O'Hara, Kimble goes undercover in Astoria, Oregon, to find Rachel and offer her immunity in exchange for testifying against Crisp in court. O'Hara is tasked with finding Rachel via her son by acting as a substitute teacher in a kindergarten class at Astoria Elementary School.  Both of them get to know each other – Kimble is divorced and has a son named Alex who is 13 years old and who he has not spoken to in a while after his ex-wife got remarried, and O'Hara is dating a chef – and become friends. However, she is incapacitated by a severe stomach flu, so Kimble takes her place as a teacher.
  The school principal, Miss Schlowski, is suspicious of Kimble's being a cop and is convinced Kimble will not last long before quitting. Though initially overwhelmed, he adapts to his new status quickly, despite not having any formal teaching experience. Through the use of his pet ferret as a class mascot, positive reinforcement, and his police training as a model for structure in class, he becomes a much admired and cherished figure to the students.
