Casper is a time traveller who arrives in the 2020s in an attempt to prevent a major future catastrophe. He meets Holly, a queer black woman he befriends and draws into his plan by giving her his knowledge of the future so that she can make quick money. However, they unwittingly alter the future themselves with their actions, until Doris, another time traveller, arrives to stop them.
