On-air radio personality Barry Champlain (Eric Bogosian) likes to push buttons -- and the envelope. The talk show host has gained popularity by being controversial, and now his show is going national. But as Barry enjoys his professional success, his personal life is unraveling. He is still battling with his ex-wife (Ellen Greene), and also receiving sizable amounts of hate mail. When Barry hits the airwaves for a lengthy session, he gets a deranged caller who just may prove to be his match.
