A mother wants to save her son, an estranged couple reconnects to look for their daughter, and Jack races against the clock to dissuade a suicide bomber.
This episode deals primarily with a young man who has been recruited to explode a vest-bomb. He gets into the hospital and ends up trapped in a hyperbaric chamber. His mother is brought in to negotiate. The romantic dalliance continues with the daughter. And there is another wrench thrown in on the Dana/Cole situation. There is a lot of suspense in this episode but we are still not half way to a resolution.
