Doc Dupree runs the successful garage in his sleepy town Caterton, ably assisted by hunky mechanic Jake Henderson, who is also devoted to the family. Doc's fashionable daughter Clare returns home, for her wedding to sweetly-doting local TJ. Also home for the event is her sister Matti, with her fancy fiance, classy businessman Devin, who balances between his workaholic socialite habits and efforts to fit in with the commoners gang, whom Jake steers to welcome him like other wedding guests, despite retaining a youth crush on Matti, who gradually reconnects with him and her original career dream: Jake's, vintage cars, and he has just the right concept.
