Sydney

You were a new guy in an assassin guild when you were discovered and fatally injured on your first job. No matter, the guild has the technology to transfer consciousness across bodies. Obviously, you would need a new identity, but there was a mixup. Instead of giving you a male identity, you were given the identity and body of a woman. Your first new target is at a pool party at a mansion. You were given an appropriate disguise for your new body and introduced to your new partner.
