A new pill has arrived at the market.
Admittedly, it has arrived at the black market, for this pill's properties should not have gotten into anybody's hands other than those of scientists working on top secret espionage work.
The person consuming such a pill is capable of completely transforming their physical body at will, without need for surgery of any kind. Upon swallowing the tablet, the consumer can transform into anything and anybody they wish to become, a very useful tool for military stealth and rescue missions of high importance.
For such a pill to fall into enemy's hands was disastrous. With its genetic recipe exposed, any drug creator can remanufacture the item, and at one point, even the average man could acquire such a miracle medicine for their own consumption.
That said, these pills are hard to acquire, and very costly in their purchase. Besides that, after some time its effects pass, and the pill's properties leave the consumer's blood stream. Unless they wish to be stuck in their new, perhaps unfinished form, the consumer might be in need of more, from wherever it came from.
One person is lucky enough to randomly come across a small packet of these miracle drugs. It has already been opened, but with their luck, one or several of these pills are still rattling inside the small container.
