four adults and a 9-month-old infant are stuck in a boat, teetering over the edge of the dam, the river ravaging below. >> that was the most strangest position i've ever seen. i knew that bow sticking up in the air like that was going to be an extreme hazard for us. >> it started as a fun day. kim and kirk medders and their 9-month-old baby elias along with two neighbors are taking a leisurely boat ride in indianapolis. they're calmly moving along when suddenly the boat's motor stops. without power, they drift down stream, ramming into a log just yards away from the dam's water. it pushes the boat back, and that's how they wound up here perched atop the dam with an underwater whirlpool swirling below. instinctually, nobody moves. >> i'm asking you to spot in case they go down, you clear?
