Marinate the filet in the soy sauce and season on each side with salt and pepper. Heat the butter in a pan and place the steak on the pan once the butter begins to foam.  You want your pan to be hot. Sear the filet for 4 minutes on each side. As you sear the steak, tilt your pan towards you allowing the butter to pool at the bottom of the pan, then pour this butter with a spoon over your filet.

Once the steak is cooked, remove the steak from the pan (do not cut it), just wrap it in foil. Now deglaze your pan with red wine and the Worcestershire sauce. Allow the wine to reduce and to thicken, then once it's developed a slight sweet flavor, pour it over the steak.

Enjoy!
