Mousetrap

Is Cameron going to revert back to her Terminating ways? Cromartie uses Charley's wife to try to lure the Connors into a trap.

The episode starts with a Charley and his wife filling up their truck at a remote gas station. In the car Michelle looks pissed as if she's thinking, "What the hell did you get me into." While Charley gets a soda, another car pulls up. A hand is shown disabling the vehicle of this newly arrived car. The unseen man steps into Charley's car with Michelle inside. It turns out that it's Cromartie, the Terminator. He drives off with the gas hose still attached.

Charley calls up Sarah and asks for her help.

Sarah along with Derek loads up in their truck and tells Cameron to keep an eye on John.

In a dark building, Charley's wife is tied up to a chair while Cromartie is nearby preparing a defense for the upcoming rescue attempt.

Meanwhile, Cameron and John pick up a computer system. While loading the two load up the truck, Riley calls John and asks to hang out. Cameron does not want to lose sight of John, but he manages to break away.

Later Agent Ellison, being relieved of duty, receives a call from Catherine Weaver who offers to pick him up for a job opportunity. She lets Ellison that she knows that 'something' may of killed his partners.

Back in Cromartie's hideout, Michelle manages to get her hand on a cell phone and calls Charley to let him know where she's at.

Derek and Sarah, who are with Charley, tell him that Michelle is being used as bait. The phone call ends with Cromartie walking up behind Michelle then duct taping her mouth.

Cromartie sets up a series of mousetraps underneath Sarah's chair rigged to explosives.

Derek, Charley and Sarah arrive at the hideout armed with guns and a grenade launcher. This is the first time I've seen someone bring a grenade launcher to a hostage situation. Sarah is no better, bringing a shotgun. Hopefully, Cromartie does not have his arm around Michelle's head.

The group walks in and finds Michelle attached to the booby trapped chair. Derek takes off to find Cromartie while Sarah instructs Michelle not to move. Michelle expresses her anger with the situation her husband got her into.

Charley goes to the truck and finds that it has been disabled by the Terminator. Sarah pulls the explosive to find that it is a fake. Derek discovers an array of computers in the building. Meanwhile, Cromartie is in another truck listening in to Sarah's cell phone call.

Derek finds wires connected to a cell phone tower and realizes that something is wrong. He gathers the group to escape.

Cromartie sets off an explosive attached to the cell phone tower, causing it to crash into the building. Everyone survives, but with the cell phone tower destroyed, Sarah loses her phone reception.

Cromartie impersonates his John mom while he calls him. He tells John that there is a change of plans and to meet him (as his mom) at the pier. John takes off, leaving Riley behind.

While this is going on, Weaver meets with Ellison and tries to enlist him to help find another Terminator.

Trying to reach John, Derek, Sarah, Michelle and Charley carjack a van and head off. On their way, Michelle cries out in pain from a deep wound inflicted during the cell phone tower collapse.

Cromartie arrives at the pier in search of John. John spots Cromartie and tries to disguise himself and runs. Cromartie fires a gun at John forcing him to dive into the water. Cromartie follows and tries to hold on to John but sinks to the bottom. John surfaces and finds Cameron overlooking on the pier. Sarah pulls up to the pier to pick up John and Cameron.

We later discover that Michelle has died from her injuries. A few days pass and Ellison and Charley attend Michelle's funeral. After the casket is lowered, Charley tosses the bible that Ellison gave to him down into Michelle's grave.
