Orphan Black movie plot

"Orphan Black" tells the story of a wandering orphan, the street chameleon Sarah witnessed a woman committing suicide and decided to pretend to be a deceased person to receive a considerable amount of savings-as it happens, Sarah and the deceased look quite similar. However, Sarah never expected that she would step into a dangerous mystery. The deceased was a police officer who was undergoing an internal investigation, which meant that Sarah had to pretend to be a policeman, and she had to accept cross-examinations that seemed clueless to her at any time. In the end Sarah discovered an amazing fact: both she and the policewoman who committed suicide were clones, and these clones were definitely more than the two of them. In order to achieve the ulterior goal, the relevant parties created a batch of cloned embryos and implanted them into the bodies of ordinary couples who did not know it, so that they could be born and grow up in different environments. No one knows who created these clones, and no one knows their ultimate purpose. These clones must find out the truth as soon as possible, otherwise it will be too late-unknown assassins are murdering them one by one .
