U.S. Marshall Elias Burch asks Matthew, still a student of law, to defend him when he's accused of murder. Daniel is forced to arrest Burch for killing Exner, an ex-con whom he had been pursuing. Rather than accept a traveling defense attorney with a drinking problem, Burch asks Matthew to defend him, claiming he was framed. But, a fiction writer who had been traveling with Exner claims to be an eyewitness, having seen Burch shoot the man in cold blood. With Burch's life in the balance and little evidence to support his claim that Exner drew a gun on him, fledgling lawyer Matthew, with help from Dr. Mike, sets out to discover what actually happened between the two sworn enemies.
