New Yorkers Jackie and Matt Lawrence get married. They are looking for a new apartment. When Matt is ambushed while jogging in the park, three retirees help him. They give the couple a comfortable but inexpensive apartment with a view of Central Park.
Matt takes out a loan from the seniors.
Shortly after moving in, another young married couple who lived in the same house disappear without a trace. Jackie and Matt find out that the old people kill young people in order to keep themselves alive longer with body substances. Several bodies are found in the basement of the house.
