There is a Wolfpack that create a plane, broken hart, boat

Locked away from society in an apartment on the Lower East Side of Manhattan, the Angulo brothers learn about the outside world through the films that they watch. Nicknamed ‘The Wolfpack’, the brothers spend their childhood reenacting their favorite films using elaborate home-made props and costumes. Their world is shaken up when one of the brothers escapes and everything changes.

This documentary looks at the Nazi submarine threat, their fleet known as the "Wolf Pack," and how it almost helped to defeat the Allies in World War II.
