Tony explains the secret operation to Palmer, supported by a recorded message from Jack. The infected body and prison break were used to persuade the Salazars that Jack had changed sides. They are potential buyers for a weaponized virus being offered by Ukrainian scientists, and CTU intends to seize it during the sale. Palmer authorizes military support while warning Tony that concealing the plan from him will have consequences. Chappelle and Michelle must also absorb how much Tony withheld.
At the ranch, Hector tries to persuade Ramon that Jack's proposal will make them rich. Ramon remains suspicious, and Claudia is furious that Jack once promised to take her away while concealing his identity. Kim tells Tony that Chase is heading into Mexico to rescue Jack without knowing the truth. Tony sends Rafael Gutierrez to intercept him, but gunmen kill Gutierrez and capture Chase after a car pursuit. Jack's effort to arrange the virus meeting now collides with his partner's arrival.
Ramon demands that Jack shoot Chase to prove his loyalty. Jack pulls the trigger against Chase's head, but the gun is empty. Ramon accepts the gesture and orders Chase interrogated. During Chase's struggle with Jack, the watch transponder is damaged, leaving CTU without Jack's signal as the group moves. In Los Angeles, Anne obtains evidence clearing her name, witnesses her ex-husband's suicide and ends her relationship with Palmer because she cannot live within his political world.
