On the eve of his 10-year class reunion, Jesse's high school sweetheart Carrie Fowler (Erika Eleniak) comes back into his life. Because of his commitment to Becky (Lisa Loughlin), Jesse (John Stamos) is reluctant to see Carrie--but the girl is very, very persistent. Elsewhere, a birthday party for Comet the dog (with an all-canine guest list) results in another crisis...and Michelle (played by the Olsen twins) just might be the cause of it all. ~ Hal Erickson, Rovi
