D.E.B.S.
(1996)

After being kidnapped by criminal mastermind Lucy, Amy finds to her surprise that Lucy is after a date and not a ransom.

For love of the law-abiding Amy, Lucy leaves behind her villainous ways (and does not, despite her wishes, explode Australia).

Amy goes on the run with her, with the blessing of her fellow D.E.B.S. who help the two escape.

Thanks Mary C!
