Nine former members of a high school baseball team reunite for the first time in seven years, invited to meet again by an unknown figure. The friends begin to reminisce about times gone by, but soon realize that there are discrepancies among their memories. When they decide to open an old time capsule to dig up the truth, they find that the box they buried now has ten keyholes instead of nine; a mystery that only a tenth person could have the answer to.
