You will not find the cache at the given coordinates. In order to find the cache you will need to watch two films and do some simple calculations afterwards.
Task 1
Watch the film "In Bruges". Somewhere in the second half of the film Ken, one of its heroes, has to go to meet Yuri, the local supplier of guns and other illegal items. Before Ken gets up that morning you will have a rather good look at the digital alarm clock near his bed. What time does the clock show? This will be your number A (3 digits).
Task 2
Watch the film "Slumdog Millionaire". Approximately three quarters of an hour into this film you will see an American couple leaving a Mercedes brand car and being shown around by the films hero. Several moments later - a group of Indian children decomposes parts of the car, takes off its wheels and puts bricks under the car. Write down the final 4 digits of the number on the licence plate of this car. This will be your number B (4 digits).
Task 3
Decrypt the given coordinates by using A and B as substitution ciphers (A for the first part, B for the second part, when the key ends, use it from the beginning for the remainder of the encrypted coordinate).
N 56 (38 99.99)
E 024 (68 77.09)
Please notice that the coordinates are given in the DMS form.

Warning: this is a public place (especially in the summer), so please be discrete and leave the cache container exactly where you found it.
