Three Americans, 2 soldiers and an Army nurse are the survivors of a U.S. airplane downed after straying into the airspace of an Iron Curtain country. They are now imprisoned there.
Jim Harrigan, a government official, asks Barton to organize a prison break using an athletic team. The team has no official backing by Washington.
Barton selects and trains his team and they undertake their daring mission. The team consisting of Liza Dantes, gymnast, Ed Carmondy, acrobat, Lou Brand, strongman and Barton as leader enters the prison, frees the prisoners and returns them to the United States.
