John Karna & Amadeus Serafini on Scream (2015)

MTV debuted it's new teen horror series, Scream, a television homage to the horror film franchise, which finds a group of teens targeted by a serial killer in a town haunted by the horrors of a past teen killer. John Karna stars as Noah, the geeky student obsessed with the town's killer history. While at a house party, a prank finds him stranded in the water in his underwear, forcing him to swim in a lake where the town's past killer was shot and presumed killed. When Noah runs into trouble in the water, he's rescued by his new classmate, Kieran (played by Amadeus Serafini). Both actors appear shirtless in the sequence.
