In an unusually somber episode, Shawn (Rider Strong) is upset when his ne'er-do-well father Chet (Blake Clark) comes back into his life, feeling as he does that Chet was never around for him or his half-brother Jack (Matthew Lawrence) when they really needed him. The situation takes an unexpected turn when, after eating some cake prepared by Rachel (Maitland Ward), Chet suffers a heart attack. In the hospital, father and son try to resolve their lifelong conflicts, and a reconciliation seems at hand--then tragedy strikes. ~ Hal Erickson, Rovi
