Louie De Palma is a cantankerous, acerbic taxi dispatcher in New York City. He tries to maintain order over a collection of varied and strange characters who drive for him. As he bullies and insults them from the safety of his “cage,” they form a special bond among themselves, becoming friends and supporting each other through the inevitable trials and tribulations of life.
Zena comes to the garage and announces she's getting married and asks the gang to let Louie know that she wants to speak with him. After telling Louie, he becomes convinced that she wants to get back together, and he meets her for dinner. Louie is crushed when she tells him she's getting married and wants him to attend, and he reacts very insultingly toward her. The rest of the gang goes to the wedding when Louie refuses, but afterwards he regrets not going and wishing her well, so he crashes his way on to their cruise ship (about to leave on their honeymoon). Zena and her husband are not happy to see Louie and before he can wish them well, Louie has a change of heart and starts choking the husband. After composing himself, however, he wishes them well, and Zena seems touched.
