After a hostile meeting, an unlikely friendship develops between the two. When they come across a lost girl in the jungle, they decide to take her back to her family, and the odd trio find themselves having to look out for each other.

'305' is a mockumentary detailing the misadventures of five not-so-brave members of the Spartan army charged with guarding a seemingly ordinary goat path. But when their actions lead to the death of King Leonidas and his army of 300 men, the five must find a way to redeem themselves and save Sparta from invasion.
