A bomb planted by a Croatian terrorist, Zvonko Bušić, is found at New York's Grand Central Terminal; one NYPD officer is killed trying to defuse it.

Zvonko Bušić (23 January 1946 – 1 September 2013) was a Croatian emigrant, responsible for hijacking TWA Flight 355 in September 1976. He was subsequently convicted of air piracy and spent 32 years in prison in the United States before being released on parole and deported in July 2008.
