While driving home, Sean is broadsided by another car & rushed to the hospital. He was saved from major injury by his vehicle's safety devices, but his view of life has changed. Inspired by a patient, Joel Gideon (DOUG SAVANT), who suffered severe frostbite trying to conquer Mount Everest, Sean plans a shark-diving trip with Matt. Sean intends to prove to Matt--and himself--that he is not a wimp, but when a tragedy occurs on the boat before they can even get into the water, Sean ends up impressing Matt for much more important reasons.
