Greetings from Tucson is a situation comedy about the life of an ethnically mixed, upwardly mobile family. The stories are seen through the eyes of 15-year-old David Tiant. His father Joaquin is a proud, pragmatic Mexican-American; his mother is a feisty Irish-American. His older sister is a socially-active cheerleader who rejects her Mexican roots and insists she is Spanish. Greetings from Tucson attempts to examine the themes of cultural identity, family and class.
