I come back

Tobias (36) lives a lonely and taciturn life. His days go by
in the solitude of his apartment. His few contacts with the
outside are thanks to the visits of his best friend Diego and to
help his father-in-law Hector, who lives alone and suffers from Alzheimer's.
That monotony is interrupted when one day at the house of his father-in-law, Tobias finds the cell phone that belonged to his wife, who died in a traffic accident and of which he had completely lost track of it.
It contains the latest photos and videos of them together, but the cell phone is locked and he doesn't know how to open it.
His need to access its content will take him through emotions he thought he had lost, making his life change forever. Everything that seemed lost begins to light up or maybe not.
