A medical student has to drop out of college due to unfortunate circumstances and starts running a sweet shop. However, his boring life encounters a sudden twist when he claims to have discovered the formula for a pill that can make people happy.
The red pill and blue pill are metaphorical terms representing a choice between learning an unsettling or life-changing truth by taking the red pill or remaining in the unquestioned experience of an illusion appearing as ordinary reality with the blue pill. The pills were used as props in the 1999 film The Matrix.
