Shawn (Rider Strong) is down in the dumps after receiving a letter from his mom Virna, informing him that she isn't his real birth mother. It takes a ghostly visitation from Shawn's dad Chet (Blake Clark) to help him get his act back together...with a little help from his friends, especially Cory (Ben Savage). Elsewhere, Eric (Will Friedle) comes up with some bizarre diversionary tactics while planning a surprise birthday party for his dad Alan (William Russ). ~ Hal Erickson, Rovi
