Three liquor-store robbers, two men and a woman, kill a cop while escaping. The woman and the younger man get away, but the older killer is captured. When allowed to make his one phone call, he talks in Greek to the younger robber, telling him about Kojak's niece and the birthday party she is having in East River Park. The killers stake out the party and kidnap the little girl, demanding the leader's release as a ransom for letting the child go. Kojak uses a painting the little girl included in a ransom note to figure out where they might be headed.
