Double or Nothing

Andy was pro bookie until his $5 billion gambling ring got busted. Now he does high-stakes personal wagers. After losing a $1 million bet that his friend can't quit drugs, he offers to run a marathon despite being in horrible shape.

If he fails, he owes double. If he succeeds, he owes nothing. The plot thickens as Andy appears to cheat. At stake are $2 million and a 30-year friendship.
