Serenity

Baker Dill is a fisherman living on isolated Plymouth Island, where he spends his days taking people out to sea and pursuing a tuna he has never managed to catch. His routine changes when Karen Zariakas, the woman he once loved, asks him to take her abusive husband, Frank, on a fishing trip and kill him. Baker agrees to consider her request, but as he prepares to act, strange events around the island begin to make him question the reality he knows.
