This pilot for the TV series stars Pernell Roberts as Jim Conrad, who runs an airport, much to the chagrin of his boss, "his way." In this, two plots run - a kid whose parents are splitting up decides to take off in a little red prop plane (and Conrad talks him down), and thieves played by the handsome Tab Hunter and his truly ugly sidekicks try to steal a money shipment. Roberts was replaced by Lloyd Bridges when the show went to series.

Artist Steve Rogers is nearly murdered by spies, seeking his late father's national secrets. He is saved during surgery via a secret formula; this serum not only heals him but also gives him fantastic strength and lightning reflexes. To help solve the mystery behind his father’s murder and bring those guilty to justice, a government agency equips him with a special motorcycle loaded with gadgets and an indestructible shield. Now armed, he battles against the nation's enemies as the Sentinel of Liberty, Captain America.

Crimefighting Captain America rights more wrongs by doing battle with a fanatical terrorist who uses his deadly drug that causes accelerated aging to finance his world revolution.
