What I can tell you is that Andernach is a famous artist who is over the road fucking the neighbour one day when his daughter trips over her shoe laces and drowns in the family pool. Five years later Andernach is a broken man, begging his former wife for forgiveness. He tries to drown himself in the same pool, only to be rescued by a friend. He then follows a butterfly (his daughter wanted him to catch them with her but he chose a rendezvous with his mistress) to a hidden door that opens onto the day she died. He intends to simply save her and then perhaps alter his future, but he finds himself trapped in the past, lurching from one unintentional catastrophe to another.
