The listing, Dragnet - DVD (3 Half-Hour Episodes) has ended.
This is the description from the back of the DVD:
Dragnet, created and directed by Jack Webb, was probably the most successful police drama in TV history. Cases drawn from the actual files of the L.A.P.D. provided audiences with a view of the unglamorous, dangerous situations that plague policemen in their daily lives.
Here are the episodes included on the DVD:
1) The Big Seventeen (11-16-52)
2) The Big Betty (9-24-53)
3) The Big Boys (1-21-54)
