Indiana Jones And The Last Crusade By George Lucas

The time is the 1930s.
Indiana Jones had always managed to get into enough trouble on his own. But this time, he finds himself in the deadliest situation imaginable -- he must rescue his father, eminent professor Dr. Henry Jones, from the Nazis' clutches to keep them from discovering secret information only Dr. Jones possesses.
The perilous race is on -- to recover the most extraordinary ancient relic of all time -- and to prevent the Nazis and Dr. Jones's devious rivals from finding it first!
