Summary:

Four ordinary teenagers, going about their daily lives, are tragically killed by the effects of severe weather: A young man is crushed to death by a tornado, a 17-year-old girl is swept away and drowns in a flood, another bright and energetic soul gets buried by an avalanche, and yet another gentleman succumbs to the extreme heat of the sun.
When they arrive in Heaven, they meet their guardian angels, who grant them a reprieve: They will be endowed with power and control over each of the violent elements which killed them--wind, water, cold and heat--and told they will have a chance to live again...on the condition that they use their newfound abilities to save others from a similar fate.
