(1981)
As usual, Egon has an ingenious plan. And, as usual, it works just fine until one of the gang members makes some kind of funny error. This time, however, even Egon's life is in danger, for some international criminals try to get rid of him by throwing him into a container filled with acid. Written by E.C. Herrnsdorf be0 This is the first of the two-part finale of the Olsen Banden series (apart from the 1998 revival).

One with Yvonne, and her preparations for her silver wedding anniversary with Keld. The other with the company hoodlum who tries to kill Egon several times, including an attempt to him into a vat of all-consuming acid. Written by Bo Brandt
