My question involves business law in the state of: California

A typical Hollywood story:

Two Partners (A & B) enter into an agreement to try and sell a show. Nothing happens for sometime. Eventually, B enters into a contract with a Network to sell the show to them. B does not tell A. B receives money and credit for show. A eventually discoveres that the show has been developed and is soon to air.

Obviously, A can go after B for breach of contract. However, I feel like I'm missing something. B purposefully deceived A. If A never found out then B gets to keep 100% of the money. Now that B is caught and it is ONLY a contracts issue, B must give A 50%....what he was entitled to in the first place. So in that situation B had nothing to lose by trying to deceieve A. Is there some related torts I should be looking into that would allow for punitive damages?

So far I've looked into Breach of Implied Covenant of Good Faith & Fair Dealing and Fradulent misrepresentation. If anyone has any thoughts or ideas on the issue I would be appreciative.
