Sandy's overbearing and obnoxious mother, Sofia "the Nana" Cohen, arrives in Newport Beach to celebrate Passover, but she also brings not only her unattainable attitude, but some bad news that she's dying from cancer. Meanwhile, Ryan searches for Marissa who has gone missing after inadvertently learning about her mother and Luke, and Ryan finds her in the most unexpected of places: at Theresa's house in Chino. Also, Summer tries to impress the Nana by knowing the traditions of Judeaisum, while Jimmy and Hailey take a step forward with their own newfound romance.
