Special Agent Jo Pullinger is thrilled to chaperone her niece's school field trip. It is supposed to be a relaxing day away from the stresses of her job. But all of it changes in an instant when the call comes in that there is a bomb on the school bus.

The bomber calls himself Graff, and he wants Jo to know that he is coming for her.

Meanwhile, Bryan Ford is starting out on his new career as a private investigator. He has promised his wife and daughter that he would take on less dangerous cases from now on, but fate has other plans for him.

When a woman goes missing, Bryan is hired to find her. But as he digs deeper into the case, he realizes that there is much more at stake than just one person's disappearance. The trail leads him straight to Graff and his twisted plot.

Now, Jo and Ford must work together to stop Graff before he can carry out his deadly plan. But with time running out and the odds stacked against them, it's anyone's guess whether they'll be able to succeed.
