Two colleagues become stranded on a deserted island, the only survivors of a plane crash. On the island, they must overcome past grievances and work together to survive, but ultimately, it's a battle of wills and wits to make it out alive.

Putting director Sam Raimi's penchant for diabolical mayhem to great use, Send Help doesn't need any assistance in thrills thanks to a very game Rachel McAdams and Dylan O'Brien along with a viciously clever script.

Rachel McAdams is Linda Liddle in Send Help, a Raimi-delivered, unhinged survival horror thriller that keeps you guessing and laughing -- and you best don’t confuse her kindness for weakness.
