ETERNITY is the story of a woman and her two lovers. Larry (Barry Primus) and Joan (Betty Buckley) are in their 80s and married for 65 years. Both attend a family function where Larry consumes pretzels. Larry chokes on the snack and dies. He reaches The Junction, which he assumes
is a pit stop before one is designated to heaven or hell. He notices that he looks quite young (played by Miles Teller). His AC or afterlife coordinator Anna (Da'Vine Joy Randolph) explains to him that they are relegated to that period in life when they were the happiest. Larry has a week to choose several 'worlds' where he can live until eternity. Joan is terminally ill and Larry was taking care of her. Larry requests Anna to let him be in The Junction until Joan dies and meets him. Anna makes it clear that it will be against the rules. Larry spends his week roaming around The Junction and befriends a bartender, Luke (Callum Turner). One week passes and Larry is forced to leave. As Larry is leaving, Joan dies and arrives at The Junction. She is also quite young (played by Elizabeth Olsen). Larry is overjoyed but his happiness is short lived. What happens next forms the rest of the film.
