In "Made in Jersey," Martina Garretti (Janet Montgomery), a young working-class woman from New Jersey, uses her street smarts to compete among her pedigreed Manhattan colleagues at a prestigious New York law firm. The drama premieres at 8 p.m. Sept. 28 on CBS. CBS also announced Sunday that Kristoffer Polaha ("Ringer") and Megalyn Echikunwoke ("90210") have joined the cast as series regulars. Both will appear for the first time in the episode airing Oct. 5. Polaha plays Nolan Adams, a third year attorney at Stark & Rowan who was raised in private schools and the unsupervised Hampton "getaways" and is part of Manhattan's royal literati. Echikunwoke plays Riley Prescott, a second year lawyer at Stark & Rowan and the daughter of the former U.S. Ambassador to Sweden. Professionally, Riley's worldly upbringing gives her an automatic buy-in to any case with international clients.
