Kara Zor-El (Milly Alcock) is on a planetary pub crawl to celebrate her 23rd birthday when Ruthye (Eve Ridley) entered the bar. The bar is one of those hives of wretched scum and villainy that abound in space settings and Ruthye is a teenaged girl who clearly does not belong. Ruthye offers a bounty of a well-made sword for anyone who helps her avenge the murder of her family by Krem (Matthias Schoenaerts). One rather large and thuggish monster that looks like an evil version of a teenaged mutant ninja turtle simply confiscated the sword. With a resigned sigh, Kara intervened to recover the sword, demonstrating that she was a skilled combatant despite the vast size difference.
Though Ruthye followed Kara back to her starship, Kara declined to help on her quest for revenge. However, by a miracle of bad luck, Krem appeared, poisoned Krypto - Kara's dog, and stole her starship. Krypto had three days to live unless Kara could retrieve the antidote from Krem. Now Kara was committed to finding Krem though she still wasn't keen on the revenge quest.
In order to even begin to chase Krem, Kara had to take public transport. She waited at a galactic bus stop in the middle of a field until a rocket bus arrived. Interesting. Oh, yeah, this planet had a red sun so she didn't have powers. Sounds awfully reckless. On the other hand, she was incapable of getting drunk in systems with a yellow sun. Though she had left Ruthye behind, Ruthye appeared on the space bus! In fact, Ruthye proves to have a talent of stowing away on ships. There follows fights with Sklarian Raiders, investigations, interrogations, false friends, rescues of slave girls, and more battles with brigands.
There are multiple flashbacks to detail Kara's past. Her father, Zor-El, was the brother of Superman's father. Zor-El had created a shield generator that allowed a city to escape the doomed planet of Krypton. Kara was born and raised on this floating chunk of Krypton. However, like Superman, she was sent to Earth. Superman (David Corenswet) makes several appearances, both in flashback, on facetime calls, and a homecoming scene at the end of the movie.
Based on the graphic novel Supergirl: Woman of Tomorrow, which itself was a retelling of True Grit, the movie is a hodgepodge of action scenes that are poorly stitched together. Kara tends to be a slovenly drunk, a woman who seems to be drinking away her sorrows rather than celebrating her birthday. At one point, she plops onto the toilet while leaving the door open. Um, okay. On the other hand, Ruthye is sober and clearheaded but naive beyond belief. Does this planet have no law enforcement to deal with the likes of Krem? Does she expect noble behavior among the patrons of the bar? But for the presence of Kara, Ruthye had walked into her likely enslavement by entering the bar. Did she not know that? Does not matter because Kara and Ruthye need to meet somehow. About halfway through, the pair encountered Lobo (Jason Momoa), a bounty hunter who happened to be tracking one of Krem's associates. He looks like some space Hells Angel with evil clown makeup. Yeah, this movie needed a dark edge and this character doesn't really fit. His inclusion comes off as nothing but fan service. Krem is a lazy villain. He's just competent enough to be a nuisance but not competent enough to be a threat. Whenever he and Kara fight, one or the other pull up short from securing victory. Kara could have snatched the poison cure in an early encounter, but doesn't. No, let's have something distract her. Krem has just poisoned Kara with Kryptonite, but pauses for a monologue. Sigh.
Kara is not a likable character. A woman doing a solo pub crawl is a big red flag. That she would go to a planet with a red sun to do such makes her seem suicidal. She certainly has cause to be depressed, but is drunkeness the cure? Much of the time, she looks hungover and unkempt. Even in the midst of the adventure, she is still somehow always less than 100% on account of this poison, that green sun, or those Kryptonite arrows. And what is with all the primitive melee weapons? Why are the villians running around with swords, axes, crossbows, and spiked chains?
Mediocre. Skip.
