After the End (2018)

Dealing with cancer as a result of a solar flare that wiped out half the population, Lance "Uppercut" Wilkins (Davis) has given up on everything and is just looking for the next meal. His path drastically changes when he is captured, nearly eaten, then saved by Psychs, a cannibal with a higher calling (Viera). Seeing no other path and not wanting to be eaten before he can at least get a decent meal, Lance reluctantly agrees to allow Psychs to tag along with him, unwitting to the much bigger and grander purpose that is about to befall them both.
