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.
Louie becomes scared of nuclear war after hearing someone talk on Donahue, and he sets up a bomb shelter in the garage. He schedules a weekend drill with Jeff and Tony in tow, but finds he's too ""soft"" to survive if war really broke out, since he is unwilling to throw Jim (who has stowed away in a radiation suit) out of the shelter.
