Carlos is worried when his ex Iris is reported missing, so when APD detective Grier closes the case, goes on alone, shocking TK but not telling him, and actually finds the trail of a serial rapist's spooky secret passages, but SWAT can't find anyone either. Owen is absurdly blamed by FBI Special Agent Rose Casey, even before he 'borrows' evidence and compromises a long undercover operation with Ty, who is personally motivates to target the motor-biker gang. The AFPD is called to rescue fallen from a cliff a mental patient's lover, which turns out to be his sex doll, which they must 'fail to save in treatment' so he can part with 'her' as his therapist planned.
