 In the late 1960 s, four close-knit orphans in Australia, called the December Boys because they were all born in the same month, leave their orphanage for a holiday by the sea. Having all but given up hope of ever being adopted, the friends are on a seaside holiday one summer when they hear a rumor that a seaside couple are looking to adopt one of the orphans, friendships are tested and new alliances made as the four boys compete for the chance to gain a real family.
