Kamikaze 89 (1982)

In the near future where "the combine" controls television and news, a bomb threat brings super cop Jansen to the combine's headquarters. Nothing happens, but his boss gives him four days to solve the hoax. Odd things occur: on day one there's a murder at the combine; vague references to the combine's enemy, Krysmopompas, appear; the nephew of the combine's boss confesses to the bomb threat, although he didn't do it. Jansen stays focused, interviewing employees who received special awards (printed on the paper used for the bomb threat). Is he onto something big or was the bomb threat just a prank? And what is this 31st floor rumored hidden in the 30-story combine headquarters?
