Plot summary
Kevin awakens into the realm of the undead: a hotel full of people who either believe it is real and are unaware that they are dead or are on a mission to vanquish their adversaries. Kevin is an assassin tasked with killing presidential nominee Patti Levin. Kevin saves a girl from drowning in the pool. He speaks with Kevin Sr. through his television, who is with Indigenous Australians and advises him to take Patti to "the well". Posing as a donor in order to kill Patti, Kevin discovers she is a decoy and not the real Patti Levin.
The girl is this world's representation of Patti. She agrees to go with Kevin to an ancient water well, despite knowing that he will kill her. On the way, a mystery man says Kevin will not be the same after killing Patti. Begrudgingly, Kevin pushes Patti into the well. An adult Patti asks for help and Kevin gets in the well. Patti says she won enough money on Jeopardy! to leave her husband, but was too scared to do it. Kevin holds Patti, then drowns her and returns to the world of the living.
