Eternal Sunshine of the Spotless Mind (2004)

Facing the anguish of being literally erased from his ex-girlfriend's mind, Joel Barrish makes a knee-jerk decision to undergo the same procedure to have Clementine removed from his memory as well. The only problem, Joel begins to realize he doesn’t want to forget everything while experiencing the lucid dream-like journey through their relationship. After waking up with no memory of Clementine, he meets a familiar stranger on a beach in Montauk leaving us to wonder if it’s possible to fight the inevitability of human connection, and are we doomed to repeat the past?
