Two brothers plan the robbery of a famous jewel, the eye of Nefertiti. But a policewoman and other guy want the gem as well and they coincide during the robbery. The bad guys kill a policeman and the brothers go to jail convicted of the killing. His only opportunity to show their innocence is to escape from the jail and catch the other guys when they try again to get the jewel.—Miguel A. Andrade <andrade@gredos.cnb.uam.es>
