"Arrow's" Emily Bett Rickards, "The Flash" star Tom Cavanagh and "Once Upon a Time's" Josh Dallas join forces in a new teaser trailer for "Sidekick," a short film that finds a dying father struggling to connect with his son through his love of heroes.

The short film, which releases on Friday, October 28, stars Josh Dallas as a man coming to grips with his own mortality. In order to pass life lessons on to his son, he shares a bedtime story that turns his life's journey into a battle between Captain Strong (Dallas) and his nemesis (Cavanagh). Rickards plays the boy's mother as well as Captain Strong's damsel.

Written and directed by Jeff Cassidy, the short film aims to offer a blockbuster-like look at its heroes while operating on an independent budget. "Sidekick" will be available at 9:00 am on Friday, October 28th.
