Tal (Agathe Bonitzer) is the 17-year-old daughter of recent French immigrants to Israel who live in Jerusalem. Following a bomb attack on a local café, she throws a bottle into the sea near Gaza City with a message asking for an explanation. Naïm (Mahmoud Shalaby), a sensitive but aimless 20-year-old Palestinian Arabs living in Gaza, discovers the bottle and tries to answer Tal's question by initiating an email correspondence. Their mutual suspicion soon develops into a tender friendship.
