On a temporary leave from military duty in Iraq, Martin's father (guest-star Costas Mandylor) pays the Camdens a visit to help his son decide whether to forgo college for a career in professional baseball. However, the visit turns sour when Martin catches his father kissing Roxanne. Meanwhile, Chandler and Paris (guest-star Shannon Kenny) reevaluate their relationship in the wake of her ex-husband's return, and Roxanne comes to blows with Martin's aunt (guest-star Keri Lynn Pratt) over their differing views on the war in Iraq. Lastly, Vic tries to join the Marines and talks to a supervisor over the matter.
