Arnold unwittingly solves his father's dilemma -- trying to make romance and finance go hand-in-hand -- when Drummond finds himself falling for an attractive local television aerobics instructor that his company is attempting to turn into an international success. Veteran Broadway and television actress Dixie Carter is introduced in the role of fitness instructor Maggie McKinney.

Maggie's reaction to a proposed pre-nuptial agreement threatens to hamper Phillip's happiness -- but could eliminate Arnold's fear about ""inheriting"" a strict new mother and a pesky little brother.

Blinded by love, Kimberly takes an enormous and deceptive risk when she talks her father into allowing her to move into an apartment, allegedly with her girl friend.
