In The Bronx in 2013, veteran NYPD Special Operations Sergeant Ralph Sarchie and his partner Butler patrol the 46th Precinct. A domestic disturbance call comes in over the radio. Sarchie finds out that the male at the address is a former Marine. At the site of the complaint, Sarchie and Butler encounter the former Marine, Jimmy Tratner, whose wife has been badly beaten. They also notice deep scratches on the floor. Tratner flees. Sarchie catches up and makes the arrest. The officers assume that Jimmy is mentally ill or high on drugs. Sarchie and Butler are called to the Bronx Zoo after a woman has thrown her toddler into the moat surrounding the lion enclosure. They find the woman in the lemur pen. She is furiously scraping at the ground and rapidly recites the lyrics to "Break On Through (To the Other Side)". Sarchie notices a commercial painter inside the lion enclosure. He enters to interrogate the man, but is attacked by the lions and barely escapes.
