Girl Next (2021)

The story involves an unhappy couple who traffics in mind control dolls to 'the client' while at the same time conducting experiments ingesting a "Quantum" drug with otherworldly properties nicknamed Aqua Velva. When the "wrong girl" is abducted, she causes their entire program to fall apart as the experimental drug also leads them all into madness. It's hard to tell who is controlled and who is not. The 'wrong girl' (they think they abducted for the program) turns out to be a clone and assassin (though she does not know it), who is there to put an end to the operation after it fails. In the end, they all turn out to be in another experiment by nefarious hidden agencies who wish to get data on the Aqua Velva drug. Based on true events.
