Rent Body Snatchers (2014)

After receiving horrific news that she has terminal cancer, Valerie leaves her doctor's office with her sister, Melissa. While driving home together, their car suddenly stops and they are engulfed in a blinding light. Valerie blacks out and when she awakens, her sister has disappeared without a trace. Months later, Melissa is still missing, but Valerie's cancer has completely disappeared, much to the disbelief of her doctor. With the help of her boyfriend, Valerie devotes her entire life to finding her sister and has considered every possibility for her disappearance except for one - alien abduction. It would be insanity to think that aliens abducted her sister and cured her cancer...or would it?
