On the eve of Dawson's sixteenth birthday, Pacey and Andie follow her therapist's advice and throw themselves into an unabashed night of recklessness and the blues. Meanwhile, back at the Leery house, Joey is organizing a surprise party for Dawson, but the longer the guest of honor is a no show, the more she is subject to surprises of her own; Jen and Ty face up to the their potentially irreconcilable differences; and Gale and Mitch come to decisions about how to raise their son in light of their separation.
