New police recruit Ernie Sampson (Warren Munson) is afraid to reveal the fact that he stutters when under pressure. In his efforts to hide his impediment, Ernie fails to warn Officers Jim Reed (Kent McCord) and Pete Malloy (Martin Milner) that they're about to be ambushed by an armed robber. After this near-fatal incident, Ernie's training officer is all for washing the young man out of the program--but surprisingly, Jim and Pete are convinced that the rookie deserves a second chance.
