Ronald Reagan Appears as Lieutenant "Brass" Bancroft in "Muder in the Air"

As a wave of sabotage threatens the security of the country, Saxby, the head of the U.S. Secret Service, assigns agent Brass Bancroft to impersonate the deceased spy Steve Swenko.

Gabby Watters, Brass's assistant, finds a letter in the dead spy's shoe, addressed to Joe Garvey, the leader of a patriotic society that is being investigated by the Rice Committee on Unamerican Activities. Consequently, Brass, posing as Swenko, sets out to contact Garvey. Brass's task is complicated when Hilda Riker, Swenko's wife, appears at his hotel looking for her husband.
