Bitter Sweet (2005)

Elizabeth and Taylor were the perfect couple as young advertising students mentored by legendary ad-man Jack Horne. Their lives and careers diverged, however, when Elizabeth left Taylor at the altar. When Horne passes away and bequeaths control of his Bitter Sweet Ad Agency to both of his promising protégés, the two learn quickly that, in order to succeed, they'll need to bury the hatchet before they kill each other.
