The Daredevil plot
"The Greatest Of Chase Pictures!"
After his victory in the big Daytona race, driver Paul Tunney is dogged by bad luck. On his return to his hometown, he wins a race, but a young driver is killed. His sister blames Tunney and vows to kill him. At every match he participates in, he sees the girl sitting in the stands. Obsessed with her brother's death, he fails to win a single race. He decides to give up motorsport, and is persuaded by a criminal organization to work for them as a driver and to transport contraband from a secret airstrip. The police are aware of this and this leads to chases.
