Ha Kyung invites Chan Ho, who is considering changing majors, to the Aviation Operations Department’s summer training camp. But Chan Ho arrives late, and the two end up taking a later bus. Worse still, the bus departs without Chan Ho realizing Ha Kyung has gotten off at a rest stop, leaving her stranded with no bag and no phone.
Just then, Woo Jin, who happens to be on his way as a special guest lecturer for the camp, appears by chance and offers her a ride. Unfortunately, their luck runs out when the car breaks down. Will this string of mishaps allow the summer training camp to end safely?
