Family Ties (1982) : 3x1

Elyse is stricken with gambling fever on a business trip to Atlantic City, and while on a roll with Alex's "foolproof" blackjack system, she's oblivious to her family and job. Excited at the prospect of having his system put to the test, Alex urges his folks to "go for the gold", but Elyse insists her trip is strictly business. Finally, she's persuaded to try her hand at blackjack. Swept away on a seemingly endless winning streak, Elyse doesn't show up at the architects' convention, ignores her family's needs and casts all financial caution to the wind.
