With school out, everyone makes big summer plans: Dawson (James Van Der Beek) heads to L.A. to work on his movie along with Audrey (Busy Philipps) who's heading home, while Jack (Kerr Smith) and Jen (Michelle Williams) plan the epic Costa Rican adventure, leaving Joey (Katie Holmes) and Pacey (Joshua Jackson) feeling perpetually stuck back in Capeside. However, all plans change when Joey and Pacey race to the airport to reclaim their loves and a special someone crosses paths with Jack.
Joey returns to Capeside for the summer and takes Audrey along for a visit, before Audrey and Dawson fly to L.A. for the summer. Pacey's taking up summer work as security at the Marina and bumps into an old friend. Jen and Jack are leaving for Costa Rica, but their flight's delayed and Grams bumps into Dawson – at the airport.
