In an effort to capture amateur video of outer space, two young brothers unexpectedly find themselves in harm's way, when an innocent science experiment becomes a day filled with unearthly events threatening their sleepy coastal town.

A blighted Los Angeles in 2009. Arthur is recently widowed, his savings wiped out by his wife's illness. Their only son is long dead. Alone, Arthur adopts and is adopted by a duckling he names Joe. Saved from suicide, Arthur's life becomes caring for Joe and keeping clean a pond on land near his son's memorial tree. Homelessness awaits Arthur, and although he experiences a great deal of unkindness - from a bus driver, motorists, and animal control officers - he also offers and finds kindness. The pond drained, Arthur and Joe head west on a picaresque journey. Is there room for angels in Los Angeles?
