Kirsten's uptight father, Caleb Nichol, comes for a visit along with his new girlfriend, Gabrielle, a 24-year-old model. Caleb does not hesitate to speak his mind and immediately angers both Sandy and Ryan, and browbeats Seth, with constant criticism with their backgrounds, while Gabrielle makes a move on Ryan. Kirsten finds her job at Caleb's company, Newport Group, in jeopardy, while Sandy considers making a change. Meanwhile, Luke approaches Marissa and tells her that he wants a second chance with her, much to Ryan's disappointment. Also, Summer makes the moves on Seth, who wonders if her feelings are real or if she just using him.
