Oscar receives a tip that a foreign agent is among those enrolled in a police academy class, so he has Jaime enroll in the same class to sniff out the imposter. Jaime soon has a suspect in her sights - her roommate Arlene. But while Arlene is not *exactly* what she appears to be, she's not the foreign agent - and Jaime's actions inadvertently reveal her to the real agent, who wastes no time ordering her death.
